LBitmapWindow::SetAutoRgnToFloater
#include "ltwrappr.h"
L_BOOL LBitmapWindow::SetAutoRgnToFloater(bAutoRgnToFloater)
L_BOOL bAutoRgnToFloater; |
/* flag that indicates whether to create the floater */ |
Enables or disables the automatic creation of a floater from a region.
Parameter |
Description |
|
bAutoRgnToFloater |
Flag that indicates whether to enable or disable the automatic creation of a floater from a region. Possible values are: |
|
|
Value |
Meaning |
|
TRUE |
[1] Enable the automatic creation of a floater from the region. This is the default value. |
|
FALSE |
[0] Disable the automatic creation of a floater from the region. |
Returns
The previous setting.
TRUE |
The previous setting was TRUE. |
FALSE |
The previous setting was FALSE. |
Comments
The view perspective is always TOP_LEFT.
If you move the floater, the original region remains unchanged.
This member function does not affect the creation of floaters using the TOOL_REGION tool. This function only affects the behavior of the Lregion functions on the LbitmapWindow().
To create a floater programmatically with no region, do the following:
RECT Rect={10,20,50,100};
m_ BitmapWindow.SetAutoRgnToFloater(TRUE);
LBitmapRgn Region(&m_ BitmapWindow);
Region.SetRgnRect(&Rect);
To create a region programmatically with no floater, do the following:
RECT Rect={10,20,50,100};
m_ BitmapWindow.SetAutoRgnToFloater(FALSE);
LBitmapRgn Region(&m_ BitmapWindow);
Region.SetRgnRect(&Rect);
