This widget is an invisible container that groups widgets into columns, rows, or a matrix, and manages their geometry. It permits exclusive or group selection of widgets.
For detailed information, please refer to PtGroup in the Photon documentation. |
This instance variable controls the behavior of the group, and may be a combination of zero or more of the following flags:
Constant | Description |
---|---|
Pt_GROUP_EXCLUSIVE | Only one child can be selected at a time. |
Pt_GROUP_EQUAL_SIZE | All children are forced to be the same height and width. |
Pt_GROUP_NO_SELECT_ALLOWED | Allows unselecting a child (click on it) without selecting another child. |
Pt_GROUP_NO_KEYS | Blocks any group use of keys. |
Pt_GROUP_NO_KEY_WRAP_HORIZONTAL | Blocks keys for horizontal wrap. |
Pt_GROUP_NO_KEY_WRAP_VERTICAL | Blocks keys for vertical wrap. |
Pt_GROUP_NO_KEY_WRAP | Blocks keys for horizontal and vertical wrap. |
Among the next 4 flags, you should not set EQUAL_SIZE and STRETCH flags for the same direction. |
Pt_GROUP_EQUAL_SIZE_HORIZONTAL | Keeps all children in the group the same width. |
Pt_GROUP_EQUAL_SIZE_VERTICAL | Keeps all children in the group the same height. |
Pt_GROUP_STRETCH_HORIZONTAL | Fills the group canvas horizontally by stretching right-hand children. |
Pt_GROUP_STRETCH_VERTICAL | Fills the group canvas vertically by stretching bottom children. |
Pt_GROUP_STRETCH | Fills the canvas in the orientation direction by stretching the widgets of that edge. |
Pt_GROUP_STRETCH_FILL | Stretch Fill |
This instance variable specifies horizontal alignment of the group as a whole, and may have one of the following values:

Pt_GROUP_HORZ_NONE | No horizontal repositioning for the group. |
Pt_GROUP_HORZ_CENTER | The group is centered horizontally. |
Pt_GROUP_HORZ_LEFT | The group is aligned to the left. |
Pt_GROUP_HORZ_RIGHT | The group is aligned to the right. |
This instance variable re-aligns child widgets into rows or columns, and may have one of the following values:
Constant | Description |
---|---|
Pt_GROUP_HORIZONTAL | Children of group are aligned in a row. |
Pt_GROUP_VERTICAL | Children of group are aligned in a column. |
Pt_GROUP_ASIS | Children of group are not aligned. |
A number specifying the number of rows or columns that the children are arranged into, for the relevant group_orientation chosen.
A number specifying the number of pixels to separate each child of the group in both the x and y directions.
This instance variable specifies vertical alignment of the group as a whole, and may have one of the following values:
Constant | Description |
---|---|
Pt_GROUP_VERT_NONE | No vertical repositioning of the group. |
