How to change the absolute position of a GUI element

[Guest]

How can i change the absolute position of an element from the mouse position. There is only function setRelativePosition.
I want to change the position of the image according to the mouse position
When i press the image , and drag the mouse it change the image position
How?

In the 2D graphics tutorial, an image follows the mouse when it's moved. You can easily adapt that to your own needs.

If you set the guiRoot as the Parent of the Element, it should also work for the relativePosition that position2d<s32>(0,0) is on the top-left corner of the screen

for example if you add a window:

Code: Select all

IGUIWindow* window;

window =guienv->addWindow (rect<s32>(position2d<s32>(0,0),dimension2d<s32>(100,100)),false, L"A Window", guienv->getRootGUIElement(),-1);

window->setRelativePosition (rect<s32>(position2d<s32>(0,0),dimension2d<s32>(100,100));

in this case, the relativePosition is equal to the absolute one, because the GUIRoot is the hole screen... or something like that... or am i wrong with this ?
i think you should try it this way... maybe it works...
