3. IupMatrix BUTTON_CB, is exported?
To implement PopUp menu context, need this:
IupSetCallback(mat, "__OLD_BUTTON_CB", (Icallback) IupGetCallback(mat,
"BUTTON_CB"));
IupSetCallback(mat, "BUTTON_CB", (Icallback) iup_popupmenu_button_cb);
To call original action BUTTON_CB.
What is different from traditional callbacks?
IupMatrix inherits from IupCanvas, but it uses several IupCanvas
callbacks. So to use an already used callback you have to do that.
But IupMatrix also exports its own callbacks. For instance, you can use
the CLICK_CB or RELEASE_CB callbacks to implement a popup menu.
Best,
Scuri
