MUI_Virtgroup
Virtgroup class generates special kinds of group objects whose children can be a lot larger than the actual group. The group acts as a (small) window through which a rectangle area of its contents is visible.
During layout, MUI tries to place the children of a virtual group in the visible part. If this is impossible, space is extended as long as all children fit.
Virtual groups themselves don't offer any scrollbars to allow user interaction. These things are handled by scrollgroup class. Usually, you don't want to use a virtual group without a scrollgroup.
| Attribute | Version | ISG | Type |
|---|---|---|---|
| MUIA_Virtgroup_Height | V6 | ..G | LONG |
| MUIA_Virtgroup_Input | V11 | I.. | BOOL |
| MUIA_Virtgroup_Left | V6 | ISG | LONG |
| MUIA_Virtgroup_Top | V6 | ISG | LONG |
| MUIA_Virtgroup_TryFit | V20 | ISG | BOOL |
| MUIA_Virtgroup_Width | V6 | ..G | LONG |
MUIA_Virtgroup_Height -- V6 [..G], LONG, 0x80423038
Read the virtual height of a virtual group.
This attribute is quite senseless, better use a scrollgroup object to control the virtual group.
MUIA_Virtgroup_Width, MUIA_Virtgroup_Left, MUIA_Virtgroup_Top
MUIA_Virtgroup_Input -- V11 [I..], BOOL, 0x80427f7e
Specify if a virtual group should be moveable by clicking into it and dragging the mouse.
Defaults to TRUE.
MUIA_Virtgroup_Left -- V6 [ISG], LONG, 0x80429371
Get/set the virtual left edge of a virtual group. The left edge will automatically be clipped to be between 0 and (VirtualWidth-DisplayWidth).
This attribute is quite senseless, better use a scrollgroup object to control the virtual group.
MUIA_Virtgroup_Width, MUIA_Virtgroup_Height, MUIA_Virtgroup_Top
MUIA_Virtgroup_Top -- V6 [ISG], LONG, 0x80425200
Get/set the virtual top edge of a virtual group. The top edge will automatically be clipped to be between 0 and (VirtualTop-DisplayTop).
This attribute is quite senseless, better use a scrollgroup object to control the virtual group.
MUIA_Virtgroup_Width, MUIA_Virtgroup_Height, MUIA_Virtgroup_Left
MUIA_Virtgroup_TryFit -- V20 [ISG], BOOL, 0x80429427
During a layout, the virtgroup will first try to force a window size large enough to fit the whole object. In case it still would not fit, the window gets resized to the maximum allowed by the screen size.
MUIA_Virtgroup_Width -- V6 [..G], LONG, 0x80427c49
Read the virtual width of a virtual group.
This attribute is quite senseless, better use a scrollgroup object to control the virtual group.
MUIA_Virtgroup_Height, MUIA_Virtgroup_Left, MUIA_Virtgroup_Top
