Suggestion: Make dragging a TColorLine easier for touch
Posted: Tue Oct 28, 2014 12:16 pm
You can do a lot of cool stuff with a TColorBandTool. Drag it around, resize it, whatever. As long as you have a mouse it works flawlessly.
Now what if we have a touchscreen? You can still move the selection around easily, but the start and end lines (which are TColorLineTools) are impossible to grab with fingers. Is there a way to increase the range the "cursor" is considered to grab the lines?
I ended up manually doing stuff in the OnMouseDown, OnMouseMove and OnMouseUp-events of the chart.
My question is not how to do it.
My question is: Is this even necessary? Did I overlook a handy and comfortable setting? If not, don't you think we should have one?
Something like myTColorBandTool.ClickTolerance := 12;?
Best regards
