{{DISPLAYTITLE:_MOUSEX}}
The '''_MOUSEX''' function returns the current horizontal(column) mouse cursor position when read after [[_MOUSEINPUT]].


{{PageSyntax}}
::: pixelcolumn% = '''_MOUSEX'''


''Usage:''
* [[SCREEN]] 0 returns the [[SINGLE]] horizontal text column position. Use [[INTEGER]] variables to avoid floating decimal returns.
* Graphic screen modes 1, 2 and 7 to 13 and [[_NEWIMAGE]] 32 bit return the [[INTEGER]] pixel columns.
* To calculate text columns in graphic modes, divide the return by 8 or the [[_FONTWIDTH]] of [[_FONT]] characters.
* [[_MOUSEINPUT]] MUST be used to detect any changes in the mouse position and is '''required''' for any coordinate returns.
* '''Note:''' In [[SCREEN]] 0, Qbasic's [[ABSOLUTE]] returned graphic coordinates. QB64 mouse functions return the text coordinates. 


''Example:'' A simple mouse drawing board using _MOUSEX and [[_MOUSEY]] coordinate values.
