NAME: GRAPHICAL_BUTTON (gb)
|
||
|
|
|
||
|
|
SYNOPSIS: Graphical push button control class
|
||
|
|
|
||
|
|
INTERFACE: GRAPHICAL_BUTTON(powin, cid, hbmMain, hbmStatus) - constructor
|
||
|
|
QueryMain() - return bitmap of picture
|
||
|
|
QueryStatus() - return status light bitmap

|
||
|
|
|
||
|
|
PARENT: PUSH_BUTTON
|
||
|
|
|
||
|
|
CAVEATS: Once a graphical button is constructed, the bitmap
|
||
|
|
belongs to the button and will be deleted when the
|
||
|
|
button is destroyed. The status light bitmap, however,
|
||
|
|
is NOT destroyed, since the same bitmaps will probably
|
||
|
|
be used by several buttons simultaneously.
|
||
|
|
|
||
|
|
NOTES: For best results, the status light bitmap (if any)
|
||
|
|
should be a 10x10 color bitmap.

||
|
|
whole button.
|

2. It allow the user specified a disable bitmap. It will
|
||
|
|
display the bitmap when the button is disable.
