General and Desktop

By setting both min width and max width of QLineEdit, the problem is solved. However, what is the proper way?

@Landolfi said in Weird drawPath problem: Comes out there was an uninitialized variable that prevent drawing. It seems that IDE always initializes memory with some value. Hi, No, the IDE as nothing to do with that. If you don't explicitly initialize your variables with a value, they will contain garbage that may or may not have any sense.

Just to update the message here in this thread, the discussion if this should be considered a bug or not is being carried at the Qt Developers mailing list. Your input on the subject would be appreciated since part of developers think that the method should not be used and the other part agrees that it is a bug.

@aha_1980 thanks, I just didn't know how to convert that.

i still have problem with numbers containing a number using the method: fixup2(QString &input). 1,2e-07 0,00012 those that contain a comma. case 'n': case 'N': input=locale().toString(baseNumber/1000000.0); break; **"120n"**results in "0,00012" and doesn't work. **"10n"**results in "1e-05" and does work. no calculatiion takes place. if(ui->lineEdit_1.toFloat() == 0.0){ QMessageBox::information(this, "empty","",QMessageBox::Ok); } this gets triggered.

@jsulm Thanks a lot for your feedback! That's fixed

Hi Just as a note external library which expects window handle. So it all comes down to if that library is available on other platforms.

Global object is defined in shared library (language: C). Maybe that's the reason.

@JonB thank you for reply , I rolled back to 5.12.4 , it is fine.

Thank you @jsulm , that's fixed.

@user4592357 I don't know, have you tried it? Does the resize for text not respect your shortened text returned from displayText()?

You can use QWidget::palette() to retrieve the palette and then use https://doc.qt.io/qt-5/qpalette.html#brush

@t0msk As I said many times apt update is only example, and if you use pkexec it will show system popup like on screenshot ... @jsulm has leapt to my defence :) And as I have said many times, my question is not about apt update but about why you need to run it or anything else sudo from your program? This equally applies if you go pkexec (though the whole point of that is it's part of polkit, and the point of polkit is that you are supposed to configure it so that it does not "show system popup like on screenshot").

@VRonin I read your links. And it works. Thank you very much.

@sankarapandiyan said in The ProgressBar doesnt close Properly: popup_progress->setValue(popup_progress->value()+1); int value = popup_progress->value() + 1; popup_progress->setValue(value); Why do you set the value twice?! Lets say popup_progress->value() is 99, then: popup_progress->setValue(popup_progress->value()+1); // here you set it to 100 int value = popup_progress->value() + 1; // value is 101 now popup_progress->setValue(value); // you set 101 here So, value is never 100 in my example!
