they say a picture is worth a thousand words;

the area between the row display and the database schema is a 4px wide bar, when the user hovers over said bar, the cursor should change, and upon mouse down, should be able to drag the line left or right. resizing the views.
I can emulate the effect with a button and lots ov scripting, is there a feature native to irrlicht that does the same thing?
Next question is; is there a window resize event? All my gui elements are placed relative to window size, if the user sets the resolution in the settings and then restarts the application it looks as it should.
However if the user just resizes the window, there is a black area or parts get cut off, depending on if you make the window bigger or smaller, as the gui elements are not sized to the window on the fly.
any help will be appreciated.
