Thanks for the replies to jenGs, Quad and 3run.
@jenGs: i remember i had such code that worked, in lite-c. The situation is changed now.
@Quad: I don't know how could be involved mouse_dir3d when there are only one panel and one text. I mentioned in the opening post i tried mouse_mode=2 and mouse_mode=4 too.
@3run: It is a pity, but your code seems to as a simple lite-c one, processed by the compiler provided by the Gamestudio.

This program is a mix of c++ and lite-c. Compiled with Qt. I would use your advises, but they are not fit into this environment.
I thought it is clear for everyone, if this post is here in External Languages chapter, i use the SDK with third party compiler.

I think i misunderstood what is the object of this function.
It is ENTITY, but not panel or text.
Thanks guys, i am sorry.

Last remark, i recognized, what i was looking for really, is the mouse_panel
