''Note: FontString:Get/SetWidth() and Get/SetHeight() behave very differently compared to usual base type funcitonality.'' | |||

FontString objects behave a little differently where SetHeight(), GetHeight(), SetWidth() and GetWidth() are concerned. | FontString objects behave a little differently where SetHeight(), GetHeight(), SetWidth() and GetWidth() are concerned. | ||

Let's assume we have a frame that is 100x100, and that we anchor our fontstring to the topleft corner only, and tell it to display a sizeable chunk of text in a 10 point font, that is ~250 pixels long if nonwrapped (i.e. [[API FontString GetStringWidth|GetStringWidth()]] would return 250). | Let's assume we have a frame that is 100x100, and that we anchor our fontstring to the topleft corner only, and tell it to display a sizeable chunk of text in a 10 point font, that is ~250 pixels long if nonwrapped (i.e. [[API FontString GetStringWidth|GetStringWidth()]] would return 250). | ||

So far, no real surprises, except for the fact that fontstrings will display without a width and height set, while other objects do not. The fun starts when we anchor more points. | So far, no real surprises, except for the fact that fontstrings will display without a width and height set, while other objects do not.

When you control the dimensions by anchoring more than one point, the drawn text will obey your points. But GetWidth() and GetHeight() continue to operate in their own little world. | When you control the dimensions by anchoring more than one point, the drawn text will obey your points.

If you want to completely clear width or height once set to have WoW start returning computed values for you, you need to call SetWidth(0) or SetHeight(0). | If you want to completely clear width or height once set to have WoW start returning computed values for you, you need to call SetWidth(0) or SetHeight(0). | ||

Note that the number returned by text:GetHeight() will typically be slighly less than the actual height of the text. Including a 5px margin (both top and bottom), the height of the frame is therefor set to the text height plus 15px. | Note that the number returned by text:GetHeight() will typically be slighly less than the actual height of the text.
