A button is a control that contains a text string,
and is one of the most common elements of a GUI. It may be placed on a
dialog box or panel, or indeed
almost any other window.
BU_LEFT |
Left-justifies the label. Windows and GTK+ only. |
BU_TOP |
Aligns the label to the top of the button. Windows and GTK+ only. |
BU_RIGHT |
Right-justifies the bitmap label. Windows and GTK+ only. |
BU_BOTTOM |
Aligns the label to the bottom of the button. Windows and GTK+ only. |
BU_EXACTFIT |
Creates the button as small as possible instead of making it of the standard size (which is the default behaviour ). |
NO_BORDER |
Creates a flat button. Windows and GTK+ only. |
See also window styles overview.
evt_button(id) { | event | … } | Process a EVT_COMMAND_BUTTON_CLICKED event,when the button is clicked. |
Constructor, creating and showing a button.
The preferred way to create standard buttons is to use default value of
label. If no label is supplied and id is one of standard IDs from
this list, standard label will be used. In addition to
that, the button will be decorated with stock icons under GTK+ 2.
ID_ANY
indicates a default value.Destructor, destroying the button.
Button creation function for two-step creation. For more details, see
Button.new.
Returns the string label for the button.
The button’s label.
Returns the default size for the buttons. It is advised to make all the dialog
buttons of the same size and this function allows to retrieve the (platform and
current font dependent size) which should be the best suited for this.
This sets the button to be the default item for the panel or dialog
box.
Under Windows, only dialog box buttons respond to this function. As
normal under Windows and Motif, pressing return causes the default button to
be depressed when the return key is pressed. See also Window#set_focus which sets the keyboard focus for windows and text panel items, and TopLevelWindow#set_default_item.
Note that under Motif, calling this function immediately after
creation of a button and before the creation of other buttons
will cause misalignment of the row of buttons, since default
buttons are larger. To get around this, call SetDefault after you have created a row of buttons: Widgets will
then set the size of all buttons currently on the panel to
the same size.
Sets the string label for the button.
