Detailed Description

wxWindow is the base class for all windows and represents any visible object om screen. All controls, top level windows and so on are windows. Sizers and device contexts are not, however, as they don't appear on screen themselves.

Please note that all children of the window will be deleted automatically by the destructor before the window itself is deleted which means that you don't have to worry about deleting them manually. Please see the window deletion overview for more information.

Also note that in this, and many others, wxWidgets classes some GetXXX() methods may be overloaded (as, for example, wxWindow::GetSize or wxWindow::GetClientSize). In this case, the overloads are non-virtual because having multiple virtual functions with the same name results in a virtual function name hiding at the derived class level (in English, this means that the derived class has to override all overloaded variants if it overrides any of them). To allow overriding them in the derived class, wxWidgets uses a unique protected virtual DoGetXXX() method and all GetXXX() ones are forwarded to it, so overriding the former changes the behaviour of the latter.

Constructor & Destructor Documentation

wxWindow::wxWindow (  ) 

Default constructor

wxWindow::wxWindow ( wxWindow *  parent,
wxWindowID  id,
const wxPoint &  pos = wxDefaultPosition,
const wxSize &  size = wxDefaultSize,
long  style = 0,
const wxString &  name = wxPanelNameStr 
)

Constructs a window, which can be a child of a frame, dialog or any other non-control window.

Parameters:
parent Pointer to a parent window.
id Window identifier. If wxID_ANY, will automatically create an identifier.
pos Window position. wxDefaultPosition indicates that wxWidgets should generate a default position for the window. If using the wxWindow class directly, supply an actual position.
size Window size. wxDefaultSize indicates that wxWidgets should generate a default size for the window. If no suitable size can be found, the window will be sized to 20x20 pixels so that the window is visible but obviously not correctly sized.
style Window style. For generic window styles, please see wxWindow.
name Window name.

virtual wxWindow::~wxWindow (  )  [virtual]

Destructor.

Deletes all sub-windows, then deletes itself. Instead of using the delete operator explicitly, you should normally use Destroy() so that wxWidgets can delete a window only when it is safe to do so, in idle time.

See also:
Window Deletion Overview, Destroy(), wxCloseEvent

Member Function Documentation

virtual bool wxWindow::AcceptsFocus (  )  const [virtual]

This method may be overridden in the derived classes to return false to indicate that this control doesn't accept input at all (i.e. behaves like e.g. wxStaticText) and so doesn't need focus.

See also:
AcceptsFocusFromKeyboard()

Reimplemented in wxPanel.

virtual bool wxWindow::AcceptsFocusFromKeyboard (  )  const [virtual]

This method may be overridden in the derived classes to return false to indicate that while this control can, in principle, have focus if the user clicks it with the mouse, it shouldn't be included in the TAB traversal chain when using the keyboard.

virtual bool wxWindow::AcceptsFocusRecursively (  )  const [virtual]

Overridden to indicate wehter this window or one of its children accepts focus. Usually it's the same as AcceptsFocus() but is overridden for container windows.

virtual void wxWindow::AddChild ( wxWindow *  child  )  [virtual]

Adds a child window. This is called automatically by window creation functions so should not be required by the application programmer. Notice that this function is mostly internal to wxWidgets and shouldn't be called by the user code.

Parameters:
child Child window to add.

virtual void wxWindow::AlwaysShowScrollbars ( bool  hflag = true,
bool  vflag = true 
) [virtual]

Call this function to force one or both scrollbars to be always shown, even if the window is big enough to show its entire contents without scrolling.

Since:
2.9.0
Parameters:
hflag Whether the horizontal scroll bar should always be visible.
vflag Whether the vertical scroll bar should always be visible.
Remarks:
This function is currently only implemented under Mac/Carbon.

void wxWindow::CacheBestSize ( const wxSize &  size  )  const

Sets the cached best size value.

virtual bool wxWindow::CanSetTransparent (  )  [virtual]

Returns true if the system supports transparent windows and calling SetTransparent() may succeed. If this function returns false, transparent windows are definitely not supported by the current system.

Reimplemented in wxTopLevelWindow.

void wxWindow::CaptureMouse (  ) 

Directs all mouse input to this window. Call ReleaseMouse() to release the capture.

Note that wxWidgets maintains the stack of windows having captured the mouse and when the mouse is released the capture returns to the window which had had captured it previously and it is only really released if there were no previous window. In particular, this means that you must release the mouse as many times as you capture it, unless the window receives the wxMouseCaptureLostEvent event.

Any application which captures the mouse in the beginning of some operation must handle wxMouseCaptureLostEvent and cancel this operation when it receives the event. The event handler must not recapture mouse.

See also:
ReleaseMouse(), wxMouseCaptureLostEvent

void wxWindow::Center ( int  dir = wxBOTH  ) 

A synonym for Centre().

void wxWindow::CenterOnParent ( int  dir = wxBOTH  ) 

A synonym for CentreOnParent().

void wxWindow::Centre ( int  direction = wxBOTH  ) 

Centres the window.

Parameters:
direction Specifies the direction for the centering. May be wxHORIZONTAL, wxVERTICAL or wxBOTH. It may also include wxCENTRE_ON_SCREEN flag if you want to center the window on the entire screen and not on its parent window.
Remarks:
If the window is a top level one (i.e. doesn't have a parent), it will be centered relative to the screen anyhow.
See also:
Center()

Reimplemented in wxDialog, and wxFrame.

void wxWindow::CentreOnParent ( int  direction = wxBOTH  ) 

Centres the window on its parent. This is a more readable synonym for Centre().

Parameters:
direction Specifies the direction for the centering. May be wxHORIZONTAL, wxVERTICAL or wxBOTH.
Remarks:
This methods provides for a way to center top level windows over their parents instead of the entire screen. If there is no parent or if the window is not a top level window, then behaviour is the same as Centre().
See also:
wxTopLevelWindow::CentreOnScreen

virtual void wxWindow::ClearBackground (  )  [virtual]

Clears the window by filling it with the current background colour. Does not cause an erase background event to be generated.

void wxWindow::ClientToScreen ( int *  x,
int *  y 
) const

Converts to screen coordinates from coordinates relative to this window.

Parameters:
x A pointer to a integer value for the x coordinate. Pass the client coordinate in, and a screen coordinate will be passed out.
y A pointer to a integer value for the y coordinate. Pass the client coordinate in, and a screen coordinate will be passed out.
wxPython Note: In place of a single overloaded method name, wxPython implements the following methods:
  • ClientToScreen(point): Accepts and returns a wxPoint
  • ClientToScreenXY(x, y): Returns a 2-tuple, (x, y)

wxPoint wxWindow::ClientToScreen ( const wxPoint &  pt  )  const

Converts to screen coordinates from coordinates relative to this window.

Parameters:
pt The client position for the second form of the function.

virtual wxSize wxWindow::ClientToWindowSize ( const wxSize &  size  )  const [virtual]

Converts client area size size to corresponding window size.

In other words, the returned value is what would GetSize() return if this window had client area of given size. Components with wxDefaultCoord value are left unchanged. Note that the conversion is not always exact, it assumes that non-client area doesn't change and so doesn't take into account things like menu bar (un)wrapping or (dis)appearance of the scrollbars.

Since:
2.8.8
See also:
WindowToClientSize()

virtual wxSize wxWindow::WindowToClientSize ( const wxSize &  size  )  const [virtual]

Converts window size size to corresponding client area size In other words, the returned value is what would GetClientSize() return if this window had given window size. Components with wxDefaultCoord value are left unchanged.

Note that the conversion is not always exact, it assumes that non-client area doesn't change and so doesn't take into account things like menu bar (un)wrapping or (dis)appearance of the scrollbars.

Since:
2.8.8
See also:
ClientToWindowSize()

bool wxWindow::Close ( bool  force = false  ) 

This function simply generates a wxCloseEvent whose handler usually tries to close the window. It doesn't close the window itself, however.

Parameters:
force false if the window's close handler should be able to veto the destruction of this window, true if it cannot.
Remarks:
Close calls the close handler for the window, providing an opportunity for the window to choose whether to destroy the window. Usually it is only used with the top level windows (wxFrame and wxDialog classes) as the others are not supposed to have any special OnClose() logic. The close handler should check whether the window is being deleted forcibly, using wxCloseEvent::CanVeto, in which case it should destroy the window using wxWindow::Destroy. Note that calling Close does not guarantee that the window will be destroyed; but it provides a way to simulate a manual close of a window, which may or may not be implemented by destroying the window. The default implementation of wxDialog::OnCloseWindow does not necessarily delete the dialog, since it will simply simulate an wxID_CANCEL event which is handled by the appropriate button event handler and may do anything at all. To guarantee that the window will be destroyed, call wxWindow::Destroy instead
See also:
Window Deletion Overview, Destroy(), wxCloseEvent

wxPoint wxWindow::ConvertDialogToPixels ( const wxPoint &  pt  ) 

Converts a point or size from dialog units to pixels.

For the x dimension, the dialog units are multiplied by the average character width and then divided by 4. For the y dimension, the dialog units are multiplied by the average character height and then divided by 8.

Remarks:
Dialog units are used for maintaining a dialog's proportions even if the font changes. You can also use these functions programmatically. A convenience macro is defined: 
                #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
See also:
ConvertPixelsToDialog()

wxSize wxWindow::ConvertDialogToPixels ( const wxSize &  sz  ) 

Converts a point or size from dialog units to pixels.

For the x dimension, the dialog units are multiplied by the average character width and then divided by 4. For the y dimension, the dialog units are multiplied by the average character height and then divided by 8.

Remarks:
Dialog units are used for maintaining a dialog's proportions even if the font changes. You can also use these functions programmatically. A convenience macro is defined: 
                #define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
See also:
ConvertPixelsToDialog()

wxPoint wxWindow::ConvertPixelsToDialog ( const wxPoint &  pt  ) 

Converts a point or size from pixels to dialog units.

For the x dimension, the pixels are multiplied by 4 and then divided by the average character width. For the y dimension, the pixels are multiplied by 8 and then divided by the average character height.

Remarks:
Dialog units are used for maintaining a dialog's proportions even if the font changes.
See also:
ConvertDialogToPixels()

wxSize wxWindow::ConvertPixelsToDialog ( const wxSize &  sz  ) 

Converts a point or size from pixels to dialog units.

For the x dimension, the pixels are multiplied by 4 and then divided by the average character width. For the y dimension, the pixels are multiplied by 8 and then divided by the average character height.

Remarks:
Dialog units are used for maintaining a dialog's proportions even if the font changes.
See also:
ConvertDialogToPixels()

virtual bool wxWindow::Destroy (  )  [virtual]

Destroys the window safely. Use this function instead of the delete operator, since different window classes can be destroyed differently. Frames and dialogs are not destroyed immediately when this function is called -- they are added to a list of windows to be deleted on idle time, when all the window's events have been processed. This prevents problems with events being sent to non-existent windows.

Returns:
true if the window has either been successfully deleted, or it has been added to the list of windows pending real deletion.

bool wxWindow::DestroyChildren (  ) 

Destroys all children of a window. Called automatically by the destructor.

bool wxWindow::IsBeingDeleted (  )  const

Returns true if this window is in process of being destroyed.

The top level windows are not deleted immediately but are rather scheduled for later destruction to give them time to process any pending messages, see Destroy() description.

This function returns true if this window, or one of its parent windows, is scheduled for destruction and can be useful to avoid manipulating it as it's usually useless to do something with a window which is on the point of disappearing anyhow.

bool wxWindow::Disable (  ) 

Disables the window. Same as Enable() Enable(false).

Returns:
Returns true if the window has been disabled, false if it had been already disabled before the call to this function.

virtual void wxWindow::DoUpdateWindowUI ( wxUpdateUIEvent &  event  )  [virtual]

Does the window-specific updating after processing the update event. This function is called by UpdateWindowUI() in order to check return values in the wxUpdateUIEvent and act appropriately. For example, to allow frame and dialog title updating, wxWidgets implements this function as follows:

        // do the window-specific processing after processing the update event
        void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
        {
            if ( event.GetSetEnabled() )
                Enable(event.GetEnabled());

            if ( event.GetSetText() )
            {
                if ( event.GetText() != GetTitle() )
                    SetTitle(event.GetText());
            }
        }

virtual void wxWindow::DragAcceptFiles ( bool  accept  )  [virtual]

Enables or disables eligibility for drop file events (OnDropFiles).

Parameters:
accept If true, the window is eligible for drop file events. If false, the window will not accept drop file events.
Remarks:
Windows only.

virtual bool wxWindow::Enable ( bool  enable = true  )  [virtual]

Enable or disable the window for user input. Note that when a parent window is disabled, all of its children are disabled as well and they are reenabled again when the parent is.

Parameters:
enable If true, enables the window for input. If false, disables the window.
Returns:
Returns true if the window has been enabled or disabled, false if nothing was done, i.e. if the window had already been in the specified state.
See also:
IsEnabled(), Disable(), wxRadioBox::Enable

static wxWindow* wxWindow::FindFocus (  )  [static]

Finds the window or control which currently has the keyboard focus.

Remarks:
Note that this is a static function, so it can be called without needing a wxWindow pointer.
See also:
SetFocus(), HasFocus()

wxWindow* wxWindow::FindWindow ( long  id  )  const

Find a child of this window, by id. May return this if it matches itself.

wxWindow* wxWindow::FindWindow ( const wxString &  name  )  const

Find a child of this window, by name. May return this if it matches itself.

static wxWindow* wxWindow::FindWindowById ( long  id,
wxWindow *  parent = NULL 
) [static]

Find the first window with the given id.

If parent is NULL, the search will start from all top-level frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy. The search is recursive in both cases.

See also:
FindWindow()

static wxWindow* wxWindow::FindWindowByLabel ( const wxString &  label,
wxWindow *  parent = NULL 
) [static]

Find a window by its label.

Depending on the type of window, the label may be a window title or panel item label. If parent is NULL, the search will start from all top-level frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy. The search is recursive in both cases.

See also:
FindWindow()

static wxWindow* wxWindow::FindWindowByName ( const wxString &  name,
wxWindow *  parent = NULL 
) [static]

Find a window by its name (as given in a window constructor or Create function call).

If parent is NULL, the search will start from all top-level frames and dialog boxes; if non-NULL, the search will be limited to the given window hierarchy.

The search is recursive in both cases. If no window with such name is found, FindWindowByLabel() is called.
