Seriously... How does GUIStyle.CalcSize() work?

I am trying to implement a fancy tooltip system where a line of text fits nicely into a GUI/Layout.Window. It expand out horizontally until it runs out of text or reaches a predetermined limit, and then extend vertically until it runs out of text or reaches a predetermined height limit.

I am trying to use CalcSize() to determine first if it will exceed this maximum width. That seems to work out alright. Then if it does exceed the max width I set the style's fixedWidth to my maximum width, and turn on word wrap and ask CalcSize() to report the new height. I expect it to return something that represents the height that the string will fill in that style (with the fixed width). I end up getting a number much larger than I expect for the height.

I read the other forum entries about CalcSize and they recommend using GUILayout to solve the problem. I tried this as well, but when I passed in GUILayout.MaxHeight()... it did not actually cap the height of the window.

Any thoughts, suggestions, solutions, or explanations would be most appreciated.

The function you are looking for is GUIStyle.CalcHeight. This takes the width as a parameter.

 

Thanks, that worked great!

What does CalcSize() return for height then when word wrap is on? Is it just not valid for this case?

Also, could someone give a more detailed description of what CalcMinMaxWidth() does and what it might be used for?

Thanks

 

CalcSize does not take word wrap into account. So if you have no newlines, it will return the height on one line of text + the style's vertical padding.

CalcMinMaxWidth is used by the layouting system to determine the min and max widths of a control.I honestly can't remember the details

 

Sorry to bump an age-old thread here, but as far as I can tell in Unity 3.1.0f3, CalcSize does in fact pay attention to the wordWrap property. I have to set it to false to get a useful result, which invalidates the whole point of CalcSize - I don't exactly want to know what the wrapped text length would be for the minimum-width window. Quite the opposite, I'm usually checking to see what the width would be in worst-case, and then clamping it back.

Thus, to get it to work presently, I have to set it to false before CalcSize, then true immediately after (before CalcHeight).

Fixed in the current version, possibly?

This is also for one of the custom styles in the array, if that matters.
