The parameter my defines one of the four corners of the dialog box which is to be aligned to the screen at position defined by at parameter.
The parameter at defines location on the screen.
Note : All positions starts with Horizontal option and then vertical option.
Changing position after initialization of the dialog box.
There may be a situation where same dialog box can be positioned at different location in the screen based on the event or from script output. We will use option : Position to define the new locations.
Here is an example script.
Using this we can position a dialog box in any of the four corners of the screen or at center. By using target ( of ) option we can place dialog box just to the right of a button.
Adding offset to location.
We can position the dialog box little below the top of the screen.
Same way we can position in little away from right edge of the screen.
