A couple of GUI questions

[rimbou]

1) On IGUIWindow. Is there any way to prevent irrlicht from drawing the X to close the window?
2) On IGUIListBox. It always displays an scrollbar even if it's not needed. Can you make it only appear when necessary?

I know I could change those things in the irrlicht source, but I was wondering if there is some way to do this using the IGUISkin or something else.

Thanks.

1) should be quite simple if you look at the API
2) you can set the scrollbar invisible yourself though i don't know if there's any easy way of knowing whether it's needed or not.

Yes that was very easy. getCloseButton()->setVisible(0)

2) you can set the scrollbar invisible yourself though i don't know if there's any easy way of knowing whether it's needed or not.

I guess I'll have to add a function to the IGUIListBox that returns a pointer to the IGUIScrollBar

If anyone is interested I made a patch:

Code: Select all

$ diff old --to-file=new
diff --to-file=new old/CGUIListBox.cpp new/CGUIListBox.cpp

> //! Returns a pointer to the Scroll Bar

I probably didn't use the right diff options to make the patch, so please enlienghten me on what options should I use

Try 'diff -Naurp <olddir> <newdir>'

This patch adds getScrollBar() to IGUIListBox. This is useful for example if you dont want to display the scrollbar on the listbox.
Example:

Code: Select all

ListBox->getScrollBar()->setVisible(0);

Here it is with the other options.
