QButton Properties
FieldTypeR/WDefaultSupport





AlignINTEGERRWalNoneW
Align determines how the control aligns within its parent control.
BMPSTRINGRWW
Use BMP to assign a new bitmap file, or to use BMP in a draw statement.
Examples:
DIM button AS QBUTTON
button.BMP = "whatever.bmp"
Details:
You can hold multiple images on a single bitmap, but they must be of the same size and next to each other in a horizontal row.
The "first" bitmap appears when the button is up.
The "second" bitmap appears when the button disabled.
The "third" bitmap appears when the button is down (clicked).
You have to tell Rapid-Q how many images are in your bitmap by assigning the number to NumBMPs.
BMPHandleRESOURCEWW
Assign a BMP resource handle to appear on the selected button.
Example:
$RESOURCE game_BMP AS "game.bmp"
DIM button AS QBUTTON
button.bmpHandle = game_BMP
