[SOLVED] Problem with QMessageBox

clochydd

Hi, what happens if you analyse your QString by

@
qDebug() << tmpStrTmp;
@

or show the QMessagBox with tmpStrTmp only?

valeSimu

yes, if I show only tmpStrTmp in the QMessageBox, it shows its content.

clochydd

I overlooked that - so your problem is the size of your QMessageBox?
Can you describe how it looks or post a picture?

valeSimu

By using this code

@ QString mex = "Error while reading vector. Please check in: " + tmpStrTmp ;
QMessageBox::critical(this, "Error", mex);@

the QMessageBox looks like this:

and with this code

@ QString mex = tmpStrTmp ;
QMessageBox::critical(this, "Error", mex);@

the QMessageBox looks like this:

Can you see the photos?

valeSimu

So I don't think that the problem is the size cause, the dialog adapt itself according to the content...

I can see the pictures and I think I understand your problem now and will try to simulate it here.

Hi,
I made some tests with your messages and I think your problem has something to do with the special characters in your tmpStrTmp.

valeSimu

I thought it too, maybe because there are < and >? but why I can display tmpStrTmp without problem but with the rest of the message not? strange

clochydd

You are right: it really sounds strange!
I would do this: Change all special chars by a placeholder then rebuild the string by replacing the placeholders step by step with the specials.

valeSimu

you know? I solved the problem....< and > caused the problem, I replaced them with & lt; and & gt; and worked! I think because "mex" contains html tag ( ) and so it interpreted all like html....I don't know how to explain it with the right words, but I hope you understood. Thank you Clochydd, I really appreciate your help! Have a nice day? evening? bye
