CLIENTOFFSET (read-only) (non inheritable) (since 3.3)

Returns the native container internal offset to the Client area, see the Layout Guide. Useful for IupFrame, IupTabs and IupDialog that have decorations. Can also be consulted in other containers, it will simply return "0x0".

This attribute can be used in conjunction with the POSITION attribute of a child so the coordinates of a child relative to the native parent top left corner can be obtained.

Value

"dxxdy", where dx and dy are integer values corresponding to the horizontal and vertical offsets, respectively, in pixels.

Affects

All elements that are containers, except menus.

Notes

For IupDialog is only available after the control is mapped.

In GTK and Motif, for the IupDialog, the dy value is negative when there is a menu. This occurs because in those systems the menu is placed inside the Client Area and all children must be placed below the menu.

In Windows, for the IupFrame, the value is always "0x0" the position of the child is still relative to the top-left corner of the frame. This is automatically compensated in calculation of the POSITION attribute.
