Detailed Description

A dialog box is a window with a title bar and sometimes a system menu, which can be moved around the screen.

It can contain controls and other windows and is often used to allow the user to make some choice or to answer a question.

Dialogs can be made scrollable, automatically, for computers with low resolution screens: please see Automatic Scrolled Dialogs for further details.

Dialogs usually contain either a single button allowing to close the dialog or two buttons, one accepting the changes and the other one discarding them (such button, if present, is automatically activated if the user presses the "Esc" key). By default, buttons with the standard wxID_OK and wxID_CANCEL identifiers behave as expected. Starting with wxWidgets 2.7 it is also possible to use a button with a different identifier instead, see SetAffirmativeId() and SetEscapeId().

Also notice that the CreateButtonSizer() should be used to create the buttons appropriate for the current platform and positioned correctly (including their order which is platform-dependent).

Modal and Modeless

There are two kinds of dialog, modal and modeless. A modal dialog blocks program flow and user input on other windows until it is dismissed, whereas a modeless dialog behaves more like a frame in that program flow continues, and input in other windows is still possible. To show a modal dialog you should use the ShowModal() method while to show a dialog modelessly you simply use Show(), just as with frames.

Note that the modal dialog is one of the very few examples of wxWindow-derived objects which may be created on the stack and not on the heap. In other words, while most windows would be created like this:

void AskUser()
{
MyAskDialog *dlg = new MyAskDialog(...);
if ( dlg->ShowModal() == wxID_OK )
// ...
//else: dialog was cancelled or some another button pressed
dlg->Destroy();
}
@ wxID_OK
Standard button and menu IDs.
Definition: defs.h:664

You can achieve the same result with dialogs by using simpler code:

void AskUser()
{
MyAskDialog dlg(...);
if ( dlg.ShowModal() == wxID_OK )
// ...
// no need to call Destroy() here
}

An application can define a wxCloseEvent handler for the dialog to respond to system close events.

Styles

This class supports the following styles:

  • wxCAPTION:
    Puts a caption on the dialog box.
  • wxDEFAULT_DIALOG_STYLE:
    Equivalent to a combination of wxCAPTION, wxCLOSE_BOX and wxSYSTEM_MENU (the last one is not used under Unix).
  • wxRESIZE_BORDER:
    Display a resizable frame around the window.
  • wxSYSTEM_MENU:
    Display a system menu.
  • wxCLOSE_BOX:
    Displays a close box on the frame.
  • wxMAXIMIZE_BOX:
    Displays a maximize box on the dialog.
  • wxMINIMIZE_BOX:
    Displays a minimize box on the dialog.
  • wxTHICK_FRAME:
    Display a thick frame around the window.
  • wxSTAY_ON_TOP:
    The dialog stays on top of all other windows.
  • wxNO_3D:
    This style is obsolete and doesn't do anything any more, don't use it in any new code.
  • wxDIALOG_NO_PARENT:
    By default, a dialog created with a NULL parent window will be given the application's top level window as parent. Use this style to prevent this from happening and create an orphan dialog. This is not recommended for modal dialogs.
  • wxDIALOG_EX_CONTEXTHELP:
    Under Windows, puts a query button on the caption. When pressed, Windows will go into a context-sensitive help mode and wxWidgets will send a wxEVT_HELP event if the user clicked on an application window. Note that this is an extended style and must be set by calling SetExtraStyle() before Create is called (two-step construction).
  • wxDIALOG_EX_METAL:
    On macOS, frames with this style will be shown with a metallic look. This is an extra style.

Under Unix or Linux, MWM (the Motif Window Manager) or other window managers recognizing the MHM hints should be running for any of these styles to have an effect.

Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxCloseEvent& event)

Event macros for events emitted by this class:

  • EVT_CLOSE(func):
    The dialog is being closed by the user or programmatically (see wxWindow::Close). The user may generate this event clicking the close button (typically the 'X' on the top-right of the title bar) if it's present (see the wxCLOSE_BOX style).
  • EVT_INIT_DIALOG(func):
    Process a wxEVT_INIT_DIALOG event. See wxInitDialogEvent.

Member Function Documentation

◆ AddMainButtonId()

void wxDialog::AddMainButtonId ( wxWindowID  id)

Adds an identifier to be regarded as a main button for the non-scrolling area of a dialog.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ CanDoLayoutAdaptation()

virtual bool wxDialog::CanDoLayoutAdaptation ( )
virtual

Returns true if this dialog can and should perform layout adaptation using DoLayoutAdaptation(), usually if the dialog is too large to fit on the display.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ Centre()

void wxDialog::Centre ( int  direction = wxBOTH)

Centres the dialog box on the display.

Parameters
directionMay be wxHORIZONTAL, wxVERTICAL or wxBOTH.

◆ Create()

bool wxDialog::Create ( wxWindow parent,
wxWindowID  id,
const wxString title,

const wxSize size = wxDefaultSize,
long  style = wxDEFAULT_DIALOG_STYLE,
const wxString name = wxDialogNameStr 
)

Used for two-step dialog box construction.

See also
wxDialog()

◆ CreateButtonSizer()

wxSizer* wxDialog::CreateButtonSizer ( long  flags)

Creates a sizer with standard buttons.

flags is a bit list of the following flags: wxOK, wxCANCEL, wxYES, wxNO, wxAPPLY, wxCLOSE, wxHELP, wxNO_DEFAULT.

The sizer lays out the buttons in a manner appropriate to the platform.

This function uses CreateStdDialogButtonSizer() internally for most platforms but doesn't create the sizer at all for the platforms with hardware buttons (such as smartphones) for which it sets up the hardware buttons appropriately and returns NULL, so don't forget to test that the return value is valid before using it.

◆ CreateSeparatedButtonSizer()

wxSizer* wxDialog::CreateSeparatedButtonSizer ( long  flags)

Creates a sizer with standard buttons using CreateButtonSizer() separated from the rest of the dialog contents by a horizontal wxStaticLine.

Note
Just like CreateButtonSizer(), this function may return NULL if no buttons were created.

This is a combination of CreateButtonSizer() and CreateSeparatedSizer().

◆ CreateSeparatedSizer()

wxSizer* wxDialog::CreateSeparatedSizer ( wxSizer sizer)

Returns the sizer containing the given one with a separating wxStaticLine if necessarily.

This function is useful for creating the sizer containing footer-like contents in dialog boxes. It will add a separating static line only if it conforms to the current platform convention (currently it is not added under Mac where the use of static lines for grouping is discouraged and is added elsewhere).

Since
2.9.2
Parameters
sizerThe sizer to wrap, must be non-NULL.
Returns
The sizer wrapping the input one or possibly the input sizer itself if no wrapping is necessary.

◆ CreateStdDialogButtonSizer()

wxStdDialogButtonSizer* wxDialog::CreateStdDialogButtonSizer ( long  flags)

Creates a wxStdDialogButtonSizer with standard buttons.

flags is a bit list of the following flags: wxOK, wxCANCEL, wxYES, wxNO, wxAPPLY, wxCLOSE, wxHELP, wxNO_DEFAULT.

The sizer lays out the buttons in a manner appropriate to the platform.

◆ CreateTextSizer()

wxSizer* wxDialog::CreateTextSizer ( const wxString message,
int  widthMax = -1 
)

Splits text up at newlines and places the lines into wxStaticText objects with the specified maximum width in a vertical wxBoxSizer.

If widthMax has its default value of -1, only explicit new line characters in message are taken into account. Otherwise, lines are broken either after a new line or wrapped, at word boundary, if their width would become bigger than the specified maximal width.

Parameters
messageThe text to be displayed.
widthMaxSpecifies the text's maximum width (this argument is available since version 3.1.1, previous versions always behaved as if the maximal width of -1 was specified).
See also
wxStaticText::Wrap(int width)

◆ DoLayoutAdaptation()

virtual bool wxDialog::DoLayoutAdaptation ( )
virtual

Performs layout adaptation, usually if the dialog is too large to fit on the display.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ EnableLayoutAdaptation()

static void wxDialog::EnableLayoutAdaptation ( bool  enable)
static

A static function enabling or disabling layout adaptation for all dialogs.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ EndModal()

virtual void wxDialog::EndModal ( int  retCode)
virtual

Ends a modal dialog, passing a value to be returned from the ShowModal() invocation.

Parameters
retCodeThe value that should be returned by ShowModal.
See also
ShowModal(), GetReturnCode(), SetReturnCode()

◆ GetAffirmativeId()

int wxDialog::GetAffirmativeId ( ) const

Gets the identifier of the button which works like standard OK button in this dialog.

See also
SetAffirmativeId()

◆ GetContentWindow()

virtual wxWindow* wxDialog::GetContentWindow ( ) const
virtual

Override this to return a window containing the main content of the dialog.

This is particularly useful when the dialog implements pages, such as wxPropertySheetDialog, and allows the layout adaptation code to know that only the pages need to be made scrollable.

Reimplemented in wxPropertySheetDialog.

◆ GetEscapeId()

int wxDialog::GetEscapeId ( ) const

Gets the identifier of the button to map presses of ESC button to.

See also
SetEscapeId()

◆ GetLayoutAdaptationDone()

bool wxDialog::GetLayoutAdaptationDone ( ) const

Returns true if the dialog has been adapted, usually by making it scrollable to work with a small display.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ GetLayoutAdaptationLevel()

int wxDialog::GetLayoutAdaptationLevel ( ) const

Gets a value representing the aggressiveness of search for buttons and sizers to be in the non-scrolling part of a layout-adapted dialog.

Zero switches off adaptation, and 3 allows search for standard buttons anywhere in the dialog.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ GetLayoutAdaptationMode()

wxDialogLayoutAdaptationMode wxDialog::GetLayoutAdaptationMode ( ) const

Gets the adaptation mode, overriding the global adaptation flag.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ GetLayoutAdapter()

static wxDialogLayoutAdapter* wxDialog::GetLayoutAdapter ( )
static

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ GetMainButtonIds()

wxArrayInt& wxDialog::GetMainButtonIds ( )

Returns an array of identifiers to be regarded as the main buttons for the non-scrolling area of a dialog.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ GetReturnCode()

int wxDialog::GetReturnCode ( ) const

Gets the return code for this window.

Remarks
A return code is normally associated with a modal dialog, where ShowModal() returns a code to the application.
See also
SetReturnCode(), ShowModal(), EndModal()

◆ GetToolBar()

wxToolBar* wxDialog::GetToolBar ( ) const

On PocketPC, a dialog is automatically provided with an empty toolbar.

This function allows you to access the toolbar and add tools to it. Removing tools and adding arbitrary controls are not currently supported.

This function is not available on any other platform.

Availability:  only available for the wxMSW port.

◆ Iconize()

virtual void wxDialog::Iconize ( bool  iconize = true)
virtual

Iconizes or restores the dialog.

Windows only.

Parameters
iconizeIf true, iconizes the dialog box; if false, shows and restores it.
Remarks
Note that in Windows, iconization has no effect since dialog boxes cannot be iconized. However, applications may need to explicitly restore dialog boxes under Motif which have user-iconizable frames, and under Windows calling Iconize(false) will bring the window to the front, as does Show(true).

Reimplemented from wxTopLevelWindow.

◆ IsIconized()

virtual bool wxDialog::IsIconized ( ) const
virtual

Returns true if the dialog box is iconized.

Windows only.

Remarks
Always returns false under Windows since dialogs cannot be iconized.

Reimplemented from wxTopLevelWindow.

◆ IsLayoutAdaptationEnabled()

static bool wxDialog::IsLayoutAdaptationEnabled ( )
static

A static function returning true if layout adaptation is enabled for all dialogs.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ IsMainButtonId()

bool wxDialog::IsMainButtonId ( wxWindowID  id) const

Returns true if id is in the array of identifiers to be regarded as the main buttons for the non-scrolling area of a dialog.

Availability:  only available for the wxMSW port.
See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ IsModal()

virtual bool wxDialog::IsModal ( ) const
virtual

Returns true if the dialog box is modal, false otherwise.

◆ SetAffirmativeId()

void wxDialog::SetAffirmativeId ( int  id)

Sets the identifier to be used as OK button.

When the button with this identifier is pressed, the dialog calls wxWindow::Validate() and wxWindow::TransferDataFromWindow() and, if they both return true, closes the dialog with the affirmative id return code.

Also, when the user presses a hardware OK button on the devices having one or the special OK button in the PocketPC title bar, an event with this id is generated.

By default, the affirmative id is wxID_OK.

See also
GetAffirmativeId(), SetEscapeId()

◆ SetEscapeId()

void wxDialog::SetEscapeId ( int  id)

Sets the identifier of the button which should work like the standard "Cancel" button in this dialog.

When the button with this id is clicked, the dialog is closed. Also, when the user presses ESC key in the dialog or closes the dialog using the close button in the title bar, this is mapped to the click of the button with the specified id.

By default, the escape id is the special value wxID_ANY meaning that wxID_CANCEL button is used if it's present in the dialog and otherwise the button with GetAffirmativeId() is used. Another special value for id is wxID_NONE meaning that ESC presses should be ignored. If any other value is given, it is interpreted as the id of the button to map the escape key to.

Note
This method should be used for custom modal dialog implemented in wxWidgets itself, native dialogs such as wxMessageDialog or wxFileDialog, handle ESC presses in their own way which cannot be customized.

◆ SetIcon()

void wxDialog::SetIcon ( const wxIcon icon)

Sets the icon for this dialog.

Parameters
iconThe icon to associate with this dialog.
See also
wxIcon

◆ SetIcons()

void wxDialog::SetIcons ( const wxIconBundle icons)
virtual

Sets the icons for this dialog.

Parameters
iconsThe icons to associate with this dialog.
See also
wxIconBundle

Reimplemented from wxTopLevelWindow.

◆ SetLayoutAdaptationDone()

void wxDialog::SetLayoutAdaptationDone ( bool  done)

Marks the dialog as having been adapted, usually by making it scrollable to work with a small display.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ SetLayoutAdaptationLevel()

void wxDialog::SetLayoutAdaptationLevel ( int  level)

Sets the aggressiveness of search for buttons and sizers to be in the non-scrolling part of a layout-adapted dialog.

Zero switches off adaptation, and 3 allows search for standard buttons anywhere in the dialog.

See also
Automatic Scrolled Dialogs (for more on layout adaptation)

◆ SetLayoutAdaptationMode()

void wxDialog::SetLayoutAdaptationMode ( wxDialogLayoutAdaptationMode  mode)

Sets the adaptation mode, overriding the global adaptation flag.

See also
wxDialogLayoutAdaptationMode, Automatic Scrolled Dialogs (for more on layout adaptation)

◆ SetLayoutAdapter()

static wxDialogLayoutAdapter* wxDialog::SetLayoutAdapter ( wxDialogLayoutAdapter adapter)
static

A static function for setting the current layout adapter object, returning the old adapter.

If you call this, you should delete the old adapter object.

See also
wxDialogLayoutAdapter, Automatic Scrolled Dialogs

◆ SetReturnCode()

void wxDialog::SetReturnCode ( int  retCode)

Sets the return code for this window.

A return code is normally associated with a modal dialog, where ShowModal() returns a code to the application. The function EndModal() calls SetReturnCode().

Parameters
retCodeThe integer return code, usually a control identifier.
See also
GetReturnCode(), ShowModal(), EndModal()

◆ Show()

virtual bool wxDialog::Show ( bool  show = true)
virtual

Hides or shows the dialog.

The preferred way of dismissing a modal dialog is to use EndModal().

Parameters
showIf true, the dialog box is shown and brought to the front, otherwise the box is hidden. If false and the dialog is modal, control is returned to the calling program.

Reimplemented from wxWindow.

◆ ShowModal()

virtual int wxDialog::ShowModal ( )
virtual

Shows an application-modal dialog.

Program flow does not return until the dialog has been dismissed with EndModal().

Notice that it is possible to call ShowModal() for a dialog which had been previously shown with Show(), this allows making an existing modeless dialog modal. However ShowModal() can't be called twice without intervening EndModal() calls.

Note that this function creates a temporary event loop which takes precedence over the application's main event loop (see wxEventLoopBase) and which is destroyed when the dialog is dismissed. This also results in a call to wxApp::ProcessPendingEvents().

Returns
The value set with SetReturnCode().
See also
ShowWindowModal(), ShowWindowModalThenDo(), EndModal(), GetReturnCode(), SetReturnCode()

Reimplemented in wxTextEntryDialog, wxMessageDialog, wxFontDialog, wxFileDialog, wxDirDialog, wxColourDialog, wxSingleChoiceDialog, and wxMultiChoiceDialog.

◆ ShowWindowModal()

void wxDialog::ShowWindowModal ( )

Shows a dialog modal to the parent top level window only.

Unlike ShowModal(), dialogs shown with this function only prevent the user from interacting with their parent frame only but not with the rest of the application. They also don't block the program execution but instead return immediately, as Show(), and generate a wxEVT_WINDOW_MODAL_DIALOG_CLOSED event (wxWindowModalDialogEvent) later when the dialog is closed.

Currently this function is only fully implemented in wxOSX ports, under the other platforms it behaves like ShowModal() (but also sends the above mentioned event).

See also
wxWindowModalDialogEvent, ShowWindowModalThenDo()
Since
2.9.0

◆ ShowWindowModalThenDo()

template<typename Functor >
void wxDialog::ShowWindowModalThenDo ( const Functor &  onEndModal)

Shows a dialog modal to the parent top level window only and call a functor after the dialog is closed.

Same as the other ShowWindowModal() overload, but calls the functor passed as the argument upon completion, instead of generating the wxEVT_WINDOW_MODAL_DIALOG_CLOSED event.

This form is particularly useful in combination with C++11 lambdas, when it allows writing window-modal very similarly to how ShowModal() is used (with the notable exception of not being able to create the dialog on stack):

wxWindowPtr<wxDialog> dlg(new wxMessageDialog(this, "Hello!"));
dlg->ShowWindowModalThenDo([this,dlg](int retcode){
if ( retcode == wxID_OK )
DoSomething();
// dlg is implicitly destroyed here, because the pointer was
// explicitly captured by the lambda
});
This class represents a dialog that shows a single or multi-line message, with a choice of OK,...
Definition: msgdlg.h:102
Parameters
onEndModalFunction object to call when the dialog is closed. The functor is called with a single integer argument, dialog's return code.
Note
The dialog instance must not be destroyed until onEndModal is called. The best way to ensure that is to use wxWindowPtr to hold a pointer and include it in the lambda's capture, by value (not reference!), as shown in the example above.
Since
3.0
