MouseMove, MouseDown and MouseUp Events (Continue)
Lets check out these events parameters.
Private Sub Command1_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
Each one of these events gets the same parameters:
Button, Shift, X and Y.
The Shift parameter is the same as the KeyDown
event's Shift paramater.
For example, if you'll press the Shift button while clicking
the mouse, the Shift value will be 1.
The Button parameter value is 1 if you've clicked
the left mouse button, and 2 if you've clicked the
right one.
The X and Y parameters are the X and Y coordinates of
the mouse cursor, relative to the upper left button corner.
The coordinates of the upper left button corner are (0, 0)
The coordinates of the Bottom Right button corner are (Button Width, Button Height)
You can try a little example.
Put the following line in the Command Button's MouseMove event:
Print X, Y
This line will print the X coordinate, and next to it
the Y coordinates (For example, the line:
Print "Hello", "World"
will print: Hello World).
