@class wxButton
It may be placed on a @ref wxDialog "dialog box" or on a @ref wxPanel panel,
or indeed on almost any other window.
- @beginStyleTable
- @style{wxBU_LEFT}
- Left-justifies the label. Windows and GTK+ only.
- @style{wxBU_TOP}
- Aligns the label to the top of the button. Windows and GTK+ only.
- @style{wxBU_RIGHT}
- Right-justifies the bitmap label. Windows and GTK+ only.
- @style{wxBU_BOTTOM}
- Aligns the label to the bottom of the button. Windows and GTK+ only.
- @style{wxBU_EXACTFIT}
- Creates the button as small as possible instead of making it of the
- standard size (which is the default behaviour ).
- @style{wxBU_NOTEXT}
- Disables the display of the text label in the button even if it has one
- or its id is one of the standard stock ids with an associated label:
- without using this style a button which is only supposed to show a
- bitmap but uses a standard id would display a label too.
- @style{wxBORDER_NONE}
- Creates a button without border. This is currently implemented in MSW,
- GTK2 and OSX/Carbon ports but in the latter only applies to buttons
- with bitmaps and using bitmap of one of the standard sizes only, namely
- 128*128, 48*48, 24*24 or 16*16. In all the other cases wxBORDER_NONE is
- ignored under OSX.
- @endStyleTable

By default, i.e. if none of the alignment styles are specified, the label
is centered both horizontally and vertically. If the button has both a
label and a bitmap, the alignment styles above specify the location of the
bitmap with respect to the label (however currently non-default alignment
combinations are not implemented on all platforms).
- @beginEventEmissionTable{wxCommandEvent}
- @event{EVT_BUTTON(id, func)}
- Process a wxEVT_COMMAND_BUTTON_CLICKED event, when the button is clicked.

Since version 2.9.1 wxButton supports showing both text and an image
(currently only when using wxMSW, wxGTK or wxOSX/Cocoa ports), see
SetBitmap() and SetBitmapLabel(), SetBitmapDisabled() &c methods. In the
get reasonably good behaviour on all platforms.
All of the bitmaps must be of the same size and the normal bitmap must be
- set first (to a valid bitmap), before setting any other ones.
+ set first (to a valid bitmap), before setting any other ones. Also, if the
+ size of the bitmaps is changed later, you need to change the size of the
+ normal bitmap before setting any other bitmaps with the new size (and you
+ do need to reset all of them as their original values can be lost when the
+ normal bitmap size changes).
The position of the image inside the button be configured using
SetBitmapPosition(). By default the image is on the left of the text.
- Please also notice that GTK+ uses a global setting called @c
- gtk-button-images to determine if the images should be shown in the buttons
+ Please also notice that GTK+ uses a global setting called @c gtk-button-images
+ to determine if the images should be shown in the buttons
at all. If it is off (which is the case in e.g. Gnome 2.28 by default), no
images will be shown, consistently with the native behaviour.

+ @style{wxBU_EXACTFIT}
+ By default, all buttons are made of at least the standard button size,
+ even if their contents is small enough to fit into a smaller size. This
+ is done for consistency as most platforms use buttons of the same size
+ in the native dialogs, but can be overridden by specifying this flag.
+ If it is given, the button will be made just big enough for its
+ contents. Notice that under MSW the button will still have at least the
+ standard height, even with this style, if it has a non-empty label.
