+ A text control allows text to be displayed and edited.
+
+ It may be single line or multi-line.
@beginStyleTable
- @style{wxTE_PROCESS_ENTER}:
+ @style{wxTE_PROCESS_ENTER}
The control will generate the event wxEVT_COMMAND_TEXT_ENTER
(otherwise pressing Enter key is either processed internally by the
control or used for navigation between dialog controls).
- @style{wxTE_PROCESS_TAB}:
+ @style{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.
- @style{wxTE_MULTILINE}:
+ @style{wxTE_MULTILINE}
The text control allows multiple lines.
- @style{wxTE_PASSWORD}:
+ @style{wxTE_PASSWORD}
The text will be echoed as asterisks.
- @style{wxTE_READONLY}:
+ @style{wxTE_READONLY}
The text will not be user-editable.
- @style{wxTE_RICH}:
+ @style{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.
- @style{wxTE_RICH2}:
+ @style{wxTE_RICH2}
Use rich text control version 2.0 or 3.0 under Win32, this style is
ignored under other platforms
- @style{wxTE_AUTO_URL}:
+ @style{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.
- @style{wxTE_NOHIDESEL}:
+ @style{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.
- @style{wxHSCROLL}:
+ @style{wxHSCROLL}
A horizontal scrollbar will be created and used, so that text won't
be wrapped. No effect under wxGTK1.
- @style{wxTE_NO_VSCROLL}:
+ @style{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.
- @style{wxTE_LEFT}:
+ @style{wxTE_LEFT}
The text in the control will be left-justified (default).
- @style{wxTE_CENTRE}:
+ @style{wxTE_CENTRE}
The text in the control will be centered (currently wxMSW and
wxGTK2 only).
- @style{wxTE_RIGHT}:
+ @style{wxTE_RIGHT}
The text in the control will be right-justified (currently wxMSW
and wxGTK2 only).
- @style{wxTE_DONTWRAP}:
+ @style{wxTE_DONTWRAP}
Same as wxHSCROLL style: don't wrap at all, show horizontal
scrollbar instead.
- @style{wxTE_CHARWRAP}:
+ @style{wxTE_CHARWRAP}
Wrap the lines too long to be shown entirely at any position
(wxUniv and wxGTK2 only).
- @style{wxTE_WORDWRAP}:
+ @style{wxTE_WORDWRAP}
Wrap the lines too long to be shown entirely at word boundaries
(wxUniv and wxGTK2 only).
- @style{wxTE_BESTWRAP}:
+ @style{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).
- @style{wxTE_CAPITALIZE}:
+ @style{wxTE_CAPITALIZE}
On PocketPC and Smartphone, causes the first letter to be
capitalized.
@endStyleTable
+
+ @section textctrl_text_format wxTextCtrl Text Format
+
+ The multiline text controls always store the text as a sequence of lines
+ separated by @c '\\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 @b not be used
+ as indices into the string returned by GetValue() as they're going to be
+ slightly off for platforms using @c "\\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.
+
+
+ @section textctrl_styles 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
+ @c 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):
+
+ @code
+ 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");
+ @endcode
+
+
+ @section textctrl_cpp_streams wxTextCtrl and C++ Streams
+
+ This class multiply-inherits from @c std::streambuf (except for some really
+ old compilers using non-standard iostream library), allowing code such as
+ the following:
+
+ @code
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ ostream stream(control)
+
+ stream << 123.456 << " some text\n";
+ stream.flush();
+ @endcode
+
+ Note that even if your compiler doesn't support this (the symbol
+ @c wxHAS_TEXT_WINDOW_STREAM has value of 0 then) you can still use
+ wxTextCtrl itself in a stream-like manner:
+
+ @code
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ *control << 123.456 << " some text\n";
+ @endcode
+
+ 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 @c std::cout to the text
+ control. This may be done in the following way:
+
+ @code
+ #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);
+ @endcode
+
+ But wxWidgets provides a convenient class to make it even simpler so
+ instead you may just do
+
+ @code
+ #include <iostream>
+
+ wxTextCtrl *control = new wxTextCtrl(...);
+
+ wxStreamToTextRedirector redirect(control);
+
+ // all output to cout goes into the text control until the exit from
+ // current scope
+ @endcode
+
+ See wxStreamToTextRedirector for more details.
+
+
+ @section textctrl_event_handling Event Handling.
+
+ The following commands are processed by default event handlers in
+ wxTextCtrl: @c wxID_CUT, @c wxID_COPY, @c wxID_PASTE, @c wxID_UNDO, @c
+ wxID_REDO. The associated UI update events are also processed
+ automatically, when the control has the focus.
+
+ To process input from a text control, use these event handler macros to
+ direct input to member functions that take a wxCommandEvent argument.
+
+ @beginEventTable{wxCommandEvent}
+ @event{EVT_TEXT(id, func)}
+ Respond to a wxEVT_COMMAND_TEXT_UPDATED 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 SetValue() is called); see
+ ChangeValue() for a function which does not send this event. This
+ event is however not sent during the control creation.
+ @event{EVT_TEXT_ENTER(id, func)}
+ Respond to a wxEVT_COMMAND_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.
+ @event{EVT_TEXT_URL(id, func)}
+ A mouse event occurred over an URL in the text control (wxMSW and
+ wxGTK2 only currently).
+ @event{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 SetMaxLength(), see its description.
