What am I doing wrong in this sequence ?

[Anonymous_Banned275]

The task of the attached code is to find text "Controller" in QEditText widget.
I want to change the color of the word "Controller" therefore I need its actual
physical location in the widget.

The attached shot shows that a word "Controller" exists in the widget....
However " find" fails to find it.....
Is the sequence incorrect?
Or what else is wrong ?

PS I did try another words to make sure I do not have a typo...

Hi @AnneRanch, the only thing that comes to mind, is that the cursor might already be at then end, and since QTextEdit::find() only searches forward, in that case it will return false.

So you might try either:

1. passing the QTextDocument::FindBackward flag to QTextEdit::find() (just to see if that is the issue); or
2. resetting the cursor before calling QTextEdit::find().

Note, I'm just speculating here (from perusing the Qt code), but if you only ever QTextEdit::append() to the control from empty (as opposed to setting new text via QTextEdit::setText() etc) then the internal cursor would likely be considered atEnd() to begin with, and calls to QTextEdit::append() will just keep moving the cursor to the new end each time. Then QTextEdit::find() will search forward from the end, finding nothing (because there's nothing left, after the end).

Anyway, give the above suggestions a go... they'll at least give us more info to go on :)

Cheers.

@Paul-Colby BINGO! It was the cursor position causing the "problem" . This just proves that one cannot have enough debugging code -if I checked the cursor position AFTER each "append" or reset it....
Thanks very much , appreciate your help,
