Autosize

[mikiwoz]

Does TLabel's AutoSize work?
I have a small label, and when I set the Caption property to a realy LONG caption - notthing happens, though I have AutoSize set to True.
I tried both DoAutoSize and AdjustSize after setting the caption, but I keep on getting errors:
"Error: identifier idents no member "DOAUTOSIZE" (or "ADJUSTSIZE")"
"Error: illegal expresson"

StaticText does not have WordWrap property, and therefore I cannot use it.  :?

Well, I've tried StaticText but it's AutoSize also does not work, at least for me. Is it some kind of error, or are those functionalities not implemented in the LCL yet?

I have an FPC ver 1.9.5 / Lazarus 0.9.2 beta / Linux (kernel 2.6.3)

I think it is not implemented yet.

[mikiwoz]

Any idea when it'll be implemented, then?

You can always use something like: Label1.Width:=Form1.Canvas.TextWidth(Label1.Caption);. Of course you must set Form1.Canvas.Font properties (FontName and Size) to Label1.Font props. I'm using such method and it works rather good.

Thanks for the hint, I've managed to write a little bit more sophisticated autosizing function now.
But there are two more issues, this time concerning WordWrap property:
1. When WordWrap is set to true, I cannot centre the text on the label. I suppose "it is not implementted yet"
2. When I assign some text to SomeLabel.Caption, WordWrap wraps the text properly. Now, when I resize this labell with my AutoSize implementation, text is not re-wrapped for the label's new dimensions. I worked around this problem simply (but definetely not neatly) by re-assigning the text to  the label (setting WordWrap to false and then back to true did not work).

Hmm... You can always add SomeLabel.Caption:=SomeLabel.Caption in OnResize event. However it might be not the best way . And about centering, unfortunatly I have no idea, how to do it beter...

I've tried it before, it does not work, I suppose it's due to optimization Well, anyway, thaks for the TextWidth hint. Helped a lot!
