Double-clicking a mouse handle for a layout label resizes to fit text

[nyalldawson]

Double-clicking a handle will auto-size the label to exactly fit
the contained text (growing or shrinking as needed). The opposite
side of the label will remaining fixed in place, so eg double-click
the bottom-right handle causes the bottom-right corner of the label
to move.

That's great! Unfortunately sizeForText seems a bit unreliable. It does not always compute the right size...

Unfortunately sizeForText seems a bit unreliable. It does not always compute the right size...

Have you got some examples I could check that with? I'll address in a follow up PR

@nyalldawson Any label really.

test_label_resize.zip

Here is an example project with a single layout that contains 4 labelItems:

• label1 : no html rendering, single line
• label2 : no html rendering, multiline
• label3 : html rendering, single line, no <br/>
• label4 : html rendering, single line, with <br/>
• label5 : html rendering, multiline, no <br/>
• label6 : html rendering, multiline, with <br/>

I called adjustSizeToText() on each of them. Here's the result:

[nyalldawson]

@YoannQDQ Ah, I think that'll be improved by the fix in this pr already

[nyalldawson]

@YoannQDQ also, good point regarding HTML mode, I hadn't considered that. I've now set it so that no auto-sizing happens if the label is in HTML mode
