MOUSEMOVE

The _MOUSEMOVE statement moves the mouse pointer to a new position on the screen as determined by the column and row coordinates.

Syntax

_MOUSEMOVE column%, row%

Parameters

• column% is the horizontal pixel coordinate to place the mouse pointer and can be any value from 0 to _WIDTH(0) - 1.
• row% is the vertical pixel position to place the mouse pointer and can be any value from 0 to _HEIGHT(0) - 1

Description

• Maximum coordinate values are based on a program's current SCREEN mode resolution or the pixel size set by _NEWIMAGE.
• SCREEN 0 uses text block coordinates. Coordinates off the screen area will create an "Illegal Function Call" ERROR
• Can be used to position the pointer to a default dialog button or move the cursor away from a button so it is not clicked twice.
• Does not require _MOUSEINPUT to be used, but all moves will be remembered and can be read by mouse functions.

Availability

• Versions prior to 1.000 (Version 1.000 had this function disabled for compatibility reasons.)
• Version 1.1 and up

Examples

Example: How to move the mouse cursor using remembered mouse movements. Press any key to quit.

SCREEN 12 i = _MOUSEINPUT 'start reading mouse events before INPUT to hold in memory PRINT INPUT "Move the mouse pointer and make a few clicks, then press Enter!", dummy$ _MOUSEMOVE 1, 1 DO: _LIMIT 30 count = count + 1 i = _MOUSEINPUT x = _MOUSEX: y = _MOUSEY b = _MOUSEBUTTON(1) PRINT count, x, y, b _MOUSEMOVE x, y LOOP UNTIL i = 0 OR INKEY$ > "" PRINT "Done!"

Explanation: The _MOUSEINPUT function will hold previous and _MOUSEMOVE events so press any key when you want to quit.

Note: INPUT, INPUT$ and LINE INPUT will allow continued reading of mouse events while awaiting program user input!

It is recommended that a WHILE _MOUSEINPUT: WEND loop be used immediately after to clear stored mouse events.
