scaletransform, regions, and mouseovers

[liquid8]

I am having some troubles getting my mouse overs in the correct location when using scaletransform. I am using regions to check if the mouse is over a certain drawn image or text. It seems the way i have it now that the regions are scaling correctly, but they are to the left and right of where they should be at.

 

DesignWidth/Height is the width/height the screen/form is designed to be at, CurrentWidth/Height is the screen/forms current width/height

 

In Paint:

 

scaleX = CurrentWidth / DesignWidth

scaleY = CurrentHeight / DesignHeight

myGraphics.ScaleTransform(scaleX, scaleY)

 

Public Function HitTest(myObject as Object, x as point) as Boolean

Dim rect As New Rectangle(myObject.LocX * scaleX, myObject.LocY * scaleY, myObject.Width * scaleX, myObject.Height * scaleY)

If rect.Contains(x) Then return True

End Function

 

MouseMove calls HitTest()

 

I was reading about converting the Mouse Position to the Client Position, but only saw code for C, no VB code. I have tried compensating for the desktop location of the form, and that works until it is scaled to a different size, then the positioning is off again. Am I missing something that I should be compensating for?

 

Thanks,

You can get a Point structure of the mouse pointer's position relative to the upper-left corner of any control using this method:

 

myPoint = myControl.PointToClient(Cursor.Position)

 

That might help you get further, but you'll still have to adjust for your scaletransform I guess.

Worked perfectly... thanks divil! :) I knew that function had to be in there somewhere..
