It is a *standard* window manager thing: a "withdrawn" is a window that has been unmapped (or never mapped). Just about all widget toolkits have this sort of feature, usually there is some 'window manager' interface API for this and other interactions with the window manager (such as size / geometry hints and grabbing access to the 'close/delete' window function, window resizing/moving, and things like window manager decoration and things like transient properties. (Tcl/Tk has a function 'wm' for all of that for example). Usually this is done because: 1) A bunch of complex stuff will be placed in the window and the the programmer does not want to give the user an 'interesting' view of the window being set up (think: keeping the curtian closed while the stage hands set up the scenery). 2) The window is a dialog box (or something) that gets re-used and is withdrawn when not in use. > > Currently, setting a window as withdrawn appears to just hide it (i.e. > elm_win_withdrawn_set(..., EINA_TRUE))... so what's the point, why not use > evas_object_hide(...) instead? > > Next, if we call evas_object_show(...) on a withdrawn window, should it be > unwithdrawn too?
