+ Inheritance diagram for wxTextCtrl:

Detailed Description

A text control allows text to be displayed and edited.

It may be single line or multi-line. Notice that a lot of methods of the text controls are found in the base wxTextEntry class which is a common base class for wxTextCtrl and other controls using a single line text entry field (e.g. wxComboBox).

Styles

This class supports the following styles:

  • wxTE_PROCESS_ENTER:
    The control will generate the event wxEVT_TEXT_ENTER (otherwise pressing Enter key is either processed internally by the control or used for navigation between dialog controls).
  • wxTE_PROCESS_TAB:
    The control will receive wxEVT_CHAR events for TAB pressed - normally, TAB is used for passing to the next control in a dialog instead. For the control created with this style, you can still use Ctrl-Enter to pass to the next control from the keyboard.
  • wxTE_MULTILINE:
    The text control allows multiple lines. If this style is not specified, line break characters should not be used in the controls value.
  • wxTE_PASSWORD:
    The text will be echoed as asterisks.
  • wxTE_READONLY:
    The text will not be user-editable.
  • wxTE_RICH:
    Use rich text control under Win32, this allows to have more than 64KB of text in the control even under Win9x. This style is ignored under other platforms.
  • wxTE_RICH2:
    Use rich text control version 2.0 or 3.0 under Win32, this style is ignored under other platforms
  • wxTE_AUTO_URL:
    Highlight the URLs and generate the wxTextUrlEvents when mouse events occur over them. This style is only supported for wxTE_RICH Win32 and multi-line wxGTK2 text controls.
  • wxTE_NOHIDESEL:
    By default, the Windows text control doesn't show the selection when it doesn't have focus - use this style to force it to always show it. It doesn't do anything under other platforms.
  • wxHSCROLL:
    A horizontal scrollbar will be created and used, so that text won't be wrapped. No effect under wxGTK1.
  • wxTE_NO_VSCROLL:
    For multiline controls only: vertical scrollbar will never be created. This limits the amount of text which can be entered into the control to what can be displayed in it under MSW but not under GTK2. Currently not implemented for the other platforms.
  • wxTE_LEFT:
    The text in the control will be left-justified (default).
  • wxTE_CENTRE:
    The text in the control will be centered (currently wxMSW and wxGTK2 only).
  • wxTE_RIGHT:
    The text in the control will be right-justified (currently wxMSW and wxGTK2 only).
  • wxTE_DONTWRAP:
    Same as wxHSCROLL style: don't wrap at all, show horizontal scrollbar instead.
  • wxTE_CHARWRAP:
    Wrap the lines too long to be shown entirely at any position (wxUniv and wxGTK2 only).
  • wxTE_WORDWRAP:
    Wrap the lines too long to be shown entirely at word boundaries (wxUniv and wxGTK2 only).
  • wxTE_BESTWRAP:
    Wrap the lines at word boundaries or at any other character if there are words longer than the window width (this is the default).
  • wxTE_CAPITALIZE:
    On PocketPC and Smartphone, causes the first letter to be capitalized.

Note that alignment styles (wxTE_LEFT, wxTE_CENTRE and wxTE_RIGHT) can be changed dynamically after control creation on wxMSW and wxGTK. wxTE_READONLY, wxTE_PASSWORD and wrapping styles can be dynamically changed under wxGTK but not wxMSW. The other styles can be only set during control creation.

wxTextCtrl Text Format

The multiline text controls always store the text as a sequence of lines separated by '\n' characters, i.e. in the Unix text format even on non-Unix platforms. This allows the user code to ignore the differences between the platforms but at a price: the indices in the control such as those returned by GetInsertionPoint() or GetSelection() can not be used as indices into the string returned by GetValue() as they're going to be slightly off for platforms using "\\r\\n" as separator (as Windows does).

Instead, if you need to obtain a substring between the 2 indices obtained from the control with the help of the functions mentioned above, you should use GetRange(). And the indices themselves can only be passed to other methods, for example SetInsertionPoint() or SetSelection().

To summarize: never use the indices returned by (multiline) wxTextCtrl as indices into the string it contains, but only as arguments to be passed back to the other wxTextCtrl methods. This problem doesn't arise for single-line platforms however where the indices in the control do correspond to the positions in the value string.

wxTextCtrl Styles.

Multi-line text controls support styling, i.e. provide a possibility to set colours and font for individual characters in it (note that under Windows wxTE_RICH style is required for style support). To use the styles you can either call SetDefaultStyle() before inserting the text or call SetStyle() later to change the style of the text already in the control (the first solution is much more efficient).

In either case, if the style doesn't specify some of the attributes (for example you only want to set the text colour but without changing the font nor the text background), the values of the default style will be used for them. If there is no default style, the attributes of the text control itself are used.

So the following code correctly describes what it does: the second call to SetDefaultStyle() doesn't change the text foreground colour (which stays red) while the last one doesn't change the background colour (which stays grey):

text->SetDefaultStyle(wxTextAttr(*wxRED));
text->AppendText("Red text\n");
text->SetDefaultStyle(wxTextAttr(wxNullColour, *wxLIGHT_GREY));
text->AppendText("Red on grey text\n");
text->SetDefaultStyle(wxTextAttr(*wxBLUE);
text->AppendText("Blue on grey text\n");

wxTextCtrl and C++ Streams

This class multiply-inherits from std::streambuf (except for some really old compilers using non-standard iostream library), allowing code such as the following:

wxTextCtrl *control = new wxTextCtrl(...);
ostream stream(control)
stream << 123.456 << " some text\n";
stream.flush();

Note that even if your build of wxWidgets doesn't support this (the symbol wxHAS_TEXT_WINDOW_STREAM has value of 0 then) you can still use wxTextCtrl itself in a stream-like manner:

wxTextCtrl *control = new wxTextCtrl(...);
*control << 123.456 << " some text\n";

However the possibility to create an ostream associated with wxTextCtrl may be useful if you need to redirect the output of a function taking an ostream as parameter to a text control.

Another commonly requested need is to redirect std::cout to the text control. This may be done in the following way:

#include <iostream>
wxTextCtrl *control = new wxTextCtrl(...);
std::streambuf *sbOld = std::cout.rdbuf();
std::cout.rdbuf(control);
// use cout as usual, the output appears in the text control
...
std::cout.rdbuf(sbOld);

But wxWidgets provides a convenient class to make it even simpler so instead you may just do

#include <iostream>
wxTextCtrl *control = new wxTextCtrl(...);
wxStreamToTextRedirector redirect(control);
// all output to cout goes into the text control until the exit from
// current scope

See wxStreamToTextRedirector for more details.

Event Handling.

The following commands are processed by default event handlers in wxTextCtrl: wxID_CUT, wxID_COPY, wxID_PASTE, wxID_UNDO, wxID_REDO. The associated UI update events are also processed automatically, when the control has the focus.

Events emitted by this class

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

void handlerFuncName(wxCommandEvent& event)

Event macros for events emitted by this class:

  • EVT_TEXT(id, func):
    Respond to a wxEVT_TEXT event, generated when the text changes. Notice that this event will be sent when the text controls contents changes – whether this is due to user input or comes from the program itself (for example, if wxTextCtrl::SetValue() is called); see wxTextCtrl::ChangeValue() for a function which does not send this event. This event is however not sent during the control creation.
  • EVT_TEXT_ENTER(id, func):
    Respond to a wxEVT_TEXT_ENTER event, generated when enter is pressed in a text control which must have wxTE_PROCESS_ENTER style for this event to be generated.
  • EVT_TEXT_URL(id, func):
    A mouse event occurred over an URL in the text control (wxMSW and wxGTK2 only currently).
  • EVT_TEXT_MAXLEN(id, func):
    This event is generated when the user tries to enter more text into the control than the limit set by wxTextCtrl::SetMaxLength(), see its description.

Constructor & Destructor Documentation

wxTextCtrl::wxTextCtrl ( )

Default ctor.

wxTextCtrl::wxTextCtrl ( wxWindow parent,
wxWindowID  id,
const wxString value = wxEmptyString,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxValidator validator = wxDefaultValidator,
const wxString name = wxTextCtrlNameStr 
)

Constructor, creating and showing a text control.

Parameters
parentParent window. Should not be NULL.
idControl identifier. A value of -1 denotes a default value.
valueDefault text value.
posText control position.
sizeText control size.
styleWindow style. See wxTextCtrl.
validatorWindow validator.
nameWindow name.
Remarks
The horizontal scrollbar (wxHSCROLL style flag) will only be created for multi-line text controls. Without a horizontal scrollbar, text lines that don't fit in the control's size will be wrapped (but no newline character is inserted). Single line controls don't have a horizontal scrollbar, the text is automatically scrolled so that the insertion point is always visible.
See Also
Create(), wxValidator
virtual wxTextCtrl::~wxTextCtrl ( )
virtual

Destructor, destroying the text control.

Member Function Documentation

bool wxTextCtrl::Create ( wxWindow parent,
wxWindowID  id,
const wxString value = wxEmptyString,
const wxPoint pos = wxDefaultPosition,
const wxSize size = wxDefaultSize,
long  style = 0,
const wxValidator validator = wxDefaultValidator,
const wxString name = wxTextCtrlNameStr 
)

Creates the text control for two-step construction.

This method should be called if the default constructor was used for the control creation. Its parameters have the same meaning as for the non-default constructor.

virtual void wxTextCtrl::DiscardEdits ( )
virtual

Resets the internal modified flag as if the current changes had been saved.

virtual bool wxTextCtrl::EmulateKeyPress ( const wxKeyEvent event)
virtual

This function inserts into the control the character which would have been inserted if the given key event had occurred in the text control.

The event object should be the same as the one passed to EVT_KEY_DOWN handler previously by wxWidgets. Please note that this function doesn't currently work correctly for all keys under any platform but MSW.

Returns
true if the event resulted in a change to the control, false otherwise.
virtual const wxTextAttr& wxTextCtrl::GetDefaultStyle ( ) const
virtual

Returns the style currently used for the new text.

See Also
SetDefaultStyle()
virtual int wxTextCtrl::GetLineLength ( long  lineNo) const
virtual

Gets the length of the specified line, not including any trailing newline character(s).

Parameters
lineNoLine number (starting from zero).
Returns
The length of the line, or -1 if lineNo was invalid.
virtual wxString wxTextCtrl::GetLineText ( long  lineNo) const
virtual

Returns the contents of a given line in the text control, not including any trailing newline character(s).

Parameters
lineNoThe line number, starting from zero.
Returns
The contents of the line.
virtual int wxTextCtrl::GetNumberOfLines ( ) const
virtual

Returns the number of lines in the text control buffer.

The returned number is the number of logical lines, i.e. just the count of the number of newline characters in the control + 1, for wxGTK and wxOSX/Cocoa ports while it is the number of physical lines, i.e. the count of lines actually shown in the control, in wxMSW and wxOSX/Carbon. Because of this discrepancy, it is not recommended to use this function.

Remarks
Note that even empty text controls have one line (where the insertion point is), so GetNumberOfLines() never returns 0.
virtual bool wxTextCtrl::GetStyle ( long  position,
wxTextAttr style 
)
virtual

Returns the style at this position in the text control.

Not all platforms support this function.

Returns
true on success, false if an error occurred (this may also mean that the styles are not supported under this platform).

If the return code is not wxTE_HT_UNKNOWN the row and column of the character closest to this position are returned, otherwise the output parameters are not modified.

Please note that this function is currently only implemented in wxUniv, wxMSW and wxGTK2 ports and always returns wxTE_HT_UNKNOWN in the other ports.

wxPerl Note: In wxPerl this function takes only the pt argument and returns a 3-element list (result, col, row).

Parameters
ptThe position of the point to check, in window device coordinates.
posReceives the position of the character at the given position. May be NULL.

wxPoint wxTextCtrl::PositionToCoords ( long  pos) const

Converts given text position to client coordinates in pixels.

This function allows to find where is the character at the given position displayed in the text control.

Availability:  only available for the wxMSW, wxGTK ports.
. Additionally, wxGTK only implements this method for multiline controls and wxDefaultPosition is always returned for the single line ones.

Parameters
posText position in 0 to GetLastPosition() range (inclusive).
Returns
On success returns a wxPoint which contains client coordinates for the given position in pixels, otherwise returns wxDefaultPosition.
Since
2.9.3

XYToPosition(), PositionToXY()
virtual bool wxTextCtrl::PositionToXY ( long  pos,
long *  x,
long *  y 
) const
virtual

Converts given position to a zero-based column, line number pair.

Parameters
posPosition.
xReceives zero based column number.
yReceives zero based line number.
Returns
true on success, false on failure (most likely due to a too large position parameter).

wxPerl Note: In wxPerl this function takes only the pos argument and returns a 2-element list (x, y).

XYToPosition()
bool wxTextCtrl::SaveFile ( const wxString filename = wxEmptyString,
int  fileType = wxTEXT_TYPE_ANY 
)

Saves the contents of the control in a text file.

Parameters
filenameThe name of the file in which to save the text.
fileTypeThe type of file to save. This is currently ignored in wxTextCtrl.
Returns
true if the operation was successful, false otherwise.
virtual bool wxTextCtrl::SetDefaultStyle ( const wxTextAttr style)
virtual

Changes the default style to use for the new text which is going to be added to the control using WriteText() or AppendText().

If either of the font, foreground, or background colour is not set in style, the values of the previous default style are used for them. If the previous default style didn't set them neither, the global font or colours of the text control itself are used as fall back.

However if the style parameter is the default wxTextAttr, then the default style is just reset (instead of being combined with the new style which wouldn't change it at all).

Parameters
styleThe style for the new text.
Returns
true on success, false if an error occurred (this may also mean that the styles are not supported under this platform).
