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).
|
|
|
|
@beginStyleTable
|
|
@style{wxTE_PROCESS_ENTER}
|
|
The control will generate the event @c wxEVT_TEXT_ENTER
|
|
(otherwise pressing Enter key is either processed internally by the
|
|
control or used to activate the default button of the dialog, if any).
|
|
@style{wxTE_PROCESS_TAB}
|
|
The control will receive @c 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}
|
|
The text control allows multiple lines. If this style is not
|
|
specified, line break characters should not be used in the controls
|
|
value.
|
|
@style{wxTE_PASSWORD}
|
|
The text will be echoed as asterisks.
|
|
@style{wxTE_READONLY}
|
|
The text will not be user-editable.
|
|
@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}
|
|
Use rich text control version 2.0 or 3.0 under Win32, this style is
|
|
ignored under other platforms
|
|
@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}
|
|
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}
|
|
A horizontal scrollbar will be created and used, so that text won't
|
|
be wrapped. No effect under wxGTK1.
|
|
@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}
|
|
The text in the control will be left-justified (default).
|
|
@style{wxTE_CENTRE}
|
|
The text in the control will be centered (currently wxMSW and
|
|
wxGTK2 only).
|
|
@style{wxTE_RIGHT}
|
|
The text in the control will be right-justified (currently wxMSW
|
|
and wxGTK2 only).
|
|
@style{wxTE_DONTWRAP}
|
|
Same as wxHSCROLL style: don't wrap at all, show horizontal
|
|
scrollbar instead.
|
|
@style{wxTE_CHARWRAP}
|
|
Wrap the lines too long to be shown entirely at any position
|
|
(wxUniv and wxGTK2 only).
|
|
@style{wxTE_WORDWRAP}
|
|
Wrap the lines too long to be shown entirely at word boundaries
|
|
(wxUniv and wxGTK2 only).
|
|
@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}
|
|
On PocketPC and Smartphone, causes the first letter to be
|
|
capitalized.
|
|
@endStyleTable
|
|
|
|
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.
|
|
|
|
|
|
@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 build of wxWidgets 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.
|
|
|
|
@beginEventEmissionTable{wxCommandEvent}
|
|
@event{EVT_TEXT(id, func)}
|
|
Respond to a @c 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.
|
|
@event{EVT_TEXT_ENTER(id, func)}
|
|
Respond to a @c 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.
|
|
@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 wxTextCtrl::SetMaxLength(), see its description.
