Hello, I created a custom control called TtsxColorPanel. This control sets a floating point value within a range from Min to Max by where you click within the range of the control. It works assuming that Min is 0, however I'm trying to make it work where Min is any real number, but I am justnot seeing how I can add Min into the following equation:
X is the X value of where the mouse is, and crect is the control's coordinates. Max can be any real number. Value:= (X - crect.Left) / (crect.Right - crect.Left) * Max; This works perfectly as I mentioned, if Min is 0, but now I need to add the Min variable into this and I have tried many combinations but I cannot get it to work correctly. Any suggestions? The first 2 parts of the equation calculates the ratio of where the mouse is in relation to the width of the rectangle area. If I add (Max - Min) then it just calculates it wrong, making the value go above the max if my mouse is beyond the middle point. Maybe this is a easy equation to fix, but my brain isnt working this morning =P __________________________________________________ Delphi-Talk mailing list -> [email protected] http://www.elists.org/mailman/listinfo/delphi-talk
