Tk_SetGrid, Tk_UnsetGrid - control the grid for interactive resizing
Tk_SetGrid(tkwin, reqWidth, reqHeight, widthInc, heightInc)
Tk_Window tkwin (in) Token for window.
int reqWidth (in) Width in grid units that corresponds to
the pixel dimension tkwin has requested
int reqHeight (in) Height in grid units that corresponds
to the pixel dimension tkwin has
requested via Tk_GeometryRequest.
int widthInc (in) Width of one grid unit, in pixels.
int heightInc (in) Height of one grid unit, in pixels.
Tk_SetGrid turns on gridded geometry management for tkwin's toplevel
window and specifies the geometry of the grid. Tk_SetGrid is typically
invoked by a widget when its setGrid option is true. It restricts
interactive resizing of tkwin's toplevel window so that the space
allocated to the toplevel is equal to its requested size plus or minus
even multiples of widthInc and heightInc. Furthermore, the reqWidth and
reqHeight values are passed to the window manager so that it can report
the window's size in grid units during interactive resizes. If tkwin's |
configuration changes (e.g., the size of a grid unit changes) then the |
widget should invoke Tk_SetGrid again with the new information. |
Tk_UnsetGrid cancels gridded geometry management for tkwin's toplevel |
For each toplevel window there can be at most one internal window with |
gridding enabled. If Tk_SetGrid or Tk_UnsetGrid is invoked when some |
other window is already controlling gridding for tkwin's toplevel, the |
calls for the new window have no effect.
