Programatically space/center buttons (controls)?

[cjtaylor]

Hello,

I have a bunch dynamically created buttons which are placed in a tabpage. Not all the buttons are created all the time, so what I want to do is space them equally and center them in the container which they reside programatically, like the designer does at design time. I was wondering if there is an easy way to do this?

Any hints?

Assuming they're all the same width, the formula to calculate the inter-control spacing would be:

[tt]spacing = (availablewidth - (n * controlwidth)) / (n + 1)[/tt]

The first control would start at [tt]spacing / 2[/tt], and each subsequent one would be [tt]spacing + controlwidth[/tt] further along.

Don't forget to test for the case where there's more controls than can fit in the available space ([tt]spacing[/tt] will be < 1).
