Hello there list,
I need to determine the percentage of the scroll of a group based on the current hScroll. I am scaling graphics in a group (thus changing the formattedWidth) and need to set the hScroll to the value that will keep the same objects centered in the viewable area of the group after the scaling is done. I've done some tests but can't figure out how to make all of my numbers match up to get a correct percentage. Here is an example -
* I have a group with a formattedWidth of 1033 pixels.
* During testing the highest hScroll value when scrolling this group to the right is 630.
* The width of the group is 397 pixels so the formattedWidth of the group - the actual width of the group is 636 pixels.
* The borderWidth = 2, scrollbarWidth = 0 and margins = 0
I don't know where the 6 pixel difference comes from. In tests with the groups formattedWidth set to other values the difference has ranged anywhere between 4 and 8 pixels.
Are the margins of the group still set to another value than 0?
They are by default set to 4 (and the showborder true also adds to the width of a group).
I did some more tests and I think the design of my slider is what is causing the problem. I added a call which prints out the value of formattedWidth - width - margins - borderWidth and as my custom group slider got to the end of the group the value increased. My custom slider which is part of the group itself was extending past the previous extreme right side of the group and adding a couple of more pixels to the group. Though the formattedHeight increases the highest value of hScroll for the group doesn't seem to be updated. I will keep fiddling around and see if I can pinpoint exactly what is going on though.
Thanks,
