QToolTip opacity

[minjunkim]

hi,

i want to use QToolTip transparently

i found few solutions in doc.qt

QToolTip { opacity: 100;} is the solution

i try it but does not work..

What is the correct way?

i think that i have to apply some code like this(setAttribute(Qt::WA_TranslucentBackground, true);)

What am I doing wrong?

my code is

mybutton->setToolTip("this test");

setStyleSheet("QToolTip { border: 2px solid darkkhaki; padding: 5px; border-radius: 3px; opacity: 100; }");

@minjunkim said in QToolTip opacity:

setStyleSheet("QToolTip { border: 2px solid darkkhaki; padding: 5px; border-radius: 3px; opacity: 100; }");

setStyleSheet("QToolTip { border: 2px solid darkkhaki; padding: 5px; border-radius: 3px; background-color: rgba(255,255,0,0); }");

Hi what platform are you on ?
I had issue on windows 8/10 to make it transparent.

Hi,

I 'm using the window10 platform.

Is this a platform-specific issue?

Is there any solution?

[J.Hilk]

@mrjj jep that's the issue.

on windows I have the same issues as the op with the stylesheet and on macOS It works as intended:

I never got it to work on win 10. ( worked fine in linux, win 7)
I didn't find any solutions back then but maybe
other have found way now.

@mrjj , @J-Hilk

thank you!

The information has helped a lot.

Let me try to solve it.

[minjunkim]

I gave up. I would be create custom class and use it.

I know this topic is too old but think it help anyone else.
If set stylesheet right after initialisatioin of QApplication like that

QApplication a(argc, argv);
qApp->setStyleSheet("QToolTip {opacity: 150;}"); 

it's take effect.

Then you can just change background or font colors in widgets

mybutton->setToolTip("this test");
mybutton->setStyleSheet("QToolTip {background-color: rgb(0, 0, 0); color: rgb(200, 200, 200);}");

@Dominikanetz it doesn't work on linux

@cawell which version of Qt? Unfortunately this has a direct relationship. On version 5.9, everything worked fine everywhere. At 5.12 it was broken and it worked as I mentioned above. I didn't look further
