The PegBitmapButton class supports
the following style flags:
FF_NONE | No frame. |
FF_THIN | Thin frame. |
FF_THICK | Thick 3D frame. |
FF_RAISED | Raised 3D frame. |
FF_RECESSED | Recessed 3D frame. |
AF_ENABLED |
This style flag is used to indicate that the object can be selected. |
BF_REPEAT |
If this style flag is set, a button object will generate periodic
PSF_CLICKED signals when the button is held down by the user. |
BF_SELECTED |
This style flag is actually a state flag which indicates if a button
object is currently selected. For the object to be selectable, the object's
AF_ENABLED style flag must be set. |
BF_DOWNACTION |
If this style flag is set, a button object will generate the
PSF_CLICKED signal when the button is pressed.
Normally, the signal is generated when the button is released. |
BF_FULLBORDER |
The button object is to be drawn with a full border, the normal look
for most buttons. Without this style, a thin button border will be applied. |
The PegBitmapButton class generates
the following signals:
PSF_CLICKED | Sent by any object when it is selected. |
