IupMap
Creates the native interface objects corresponding to the given IUP interface elements.
It will also create the native element of all the children in the element's tree.
Parameters/Return
int IupMap(Ihandle* ih); [in C] iup.Map(ih: iuplua-tag) -> ret: number [in Lua]
ih: Identifier of an interface element.
If the element was already mapped returns IUP_NOERROR.
If the native creation failed returns IUP_ERROR.
Return IUP_NOERROR if successful.
Notes
If the element is a dialog then the abstract layout will be updated even if the element is already mapped. If the dialog is visible the elements will be immediately repositioned.
If you add new elements to an already mapped dialog you must call IupMap for that elements. And then call IupRefresh to update the dialog layout.
If the WID attribute is NULL, it means the element was not already mapped. Some containers do not have a native element associated, like VBOX and HBOX. In this case their WID is inherited from their parent.
A child is only mapped if its parent is already mapped.
This function is automatically called before dialog show in IupShow, IupShowXY or IupPopup.
It is usefull for the application to call IupMap when the value of the WID attribute must be known, or the element mapped, before a dialog is made visible.
The MAP_CB callback is called just after the native element is created and the dialog layout updated, so it can also be used to create other things that depend on the WID attribute.
