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%
- 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.
