Description

Takes X and Y coordinates relative to the panel and returns their corresponding positions relative to the screen.

See also Panel:ScreenToLocal.

This function uses a cached value for the screen position of the panel, computed at the end of the last VGUI Think/Layout pass, so inaccurate results may be returned if the panel or any of its ancestors have been re-positioned outside of PANEL:Think or PANEL:PerformLayout within the last frame.
If the panel uses Panel:Dock, this function will return 0, 0 when the panel was created. The position will be updated in the next frame.

Arguments

1 number posX
The X coordinate of the position on the panel to translate.
2 number posY
The Y coordinate of the position on the panel to translate.

Returns

1 number
The X coordinate relative to the screen.
2 number
The Y coordinate relative to the screen.

Example: Basic Usages

Here we create a DFrame derivative and use it to display the screen coordinates of the center of the panel. For and explanation of the design structure read VGUI Creating Custom Elements
