single line TextCtrl doesn't scroll

wxtrac commented 19 years ago

Issue migrated from trac ticket # 1802

component: old wxOSX/Carbon port | priority: normal

2004-08-10 01:09:42: kasplat created the issue

The single line TextCtrl doesn't support auto-scrolling to the right as the user types text, nor does it scroll horizontally as the user tries to drag the selection. This makes it difficult to use for strings that are wider than the control width.

ka p.s. My main issue is not being able to hide a TextCtrl, but I know that you already know about that one ;-)

I'm using CVS HEAD and it works for me... thanks for the report!

Open the text control sample, and on ANY of the single line text controls (except the read-only one), start typing. When you get to the right edge, the cursor just goes off screen, and you can't see what you're typing. Likewise, highlighting and going to the right or left where there is material offscreen does not cause the single line text to scroll.

I'm using a slightly outdated HEAD (about 2 weeks) but not much has changed on the Mac during that time, mostly warning fixes and secondary classes like cursor that wouldn't affect this. Nor have I seen any changes that look like they would affect this, unless this functionality is really hidden somewhere (or your GetLineLength change actually fixed this). I'm avoiding HEAD right now because of the wx-config changes.

I just want to be sure this is actually fixed and wasn't misunderstood, sorry if it seems like 2nd guessing but this is an important one to me as well.

Specific to 10.3.

Right. I don't have 10.3 - so I'll have to leave this one up to stefan.

as we cannot fix or extend the behaviour of the built-in HITextView could you please switch the version trigger in line 377 of textctrl.cpp from 0x1030 to 0x1040 and report me any problems you encounter on 10.3.X when using the 'old' MLTE based implementation

Thanks,

Stefan

I made the change and now if the textctrl has the focus when the top-level parent is destroyed I get a crash. Here is the top of the stack trace:

Single-line text controls now use non-HIView implementation which does support horizontal scrolling. That's why it always worked on 10.2--10.2 has never used the HIView control.
