    Hello everyone,

    I am currently trying to develop a GUI for a desktop application. I am using QPropertyAnimation and QGraphicsOpacityEffect to create moving navigation bars, as well as moving buttons with fade in/out effects.

    I get spammed with warnings when I click the buttons to run the animations. This is my first time animating with Qt C++/XML so please bear with me! I am hoping that someone can point me in the right direction. If you notice anything else wrong with the code, please feel free to let me know!

    Desktop Qt 6.1.2 MinGW 64-bit - Qt Creator 5.0.1, based on Qt 5.15.2.

    Warnings:

QPainter::translate: Painter not active
QPainter::restore: Unbalanced save/restore
QPainter::worldTransform: Painter not active

    Hi and welcome to devnet,

    Since you do not keep the animation, I would use the parameter of the start method to let it be destroyed appropriately. See if that improves the situation.

    @SGaist Thanks for the response!

    I replaced all the start() functions with start(QAbstractAnimation::DeleteWhenStopped), but I'm still getting the same warnings whenever I click the navigation buttons.

    Is it a requirement to use the save/restore functions for this type of animation, as I get the odd message about unbalanced save/restore? This is the qDebug+Warning output from a single button click:

    Can you provide a minimal compilable example that reproduces this ?

    Did you try with 6.2 since was released yesterday ?

    Thanks for taking the time! I have tried with the following compilers, all issuing the same warnings;

    Qt 6.1.2 MinGW & MSVC 2019 64-bit
    Qt 5.12.11 MinGW 64-bit & 32-bit
    Qt 5.12.11 MSVC 2017 64-bit

    I have cleaned up the code and made a GitHub Gist as I kept hitting the character limit for the forums. If you would like it in another format, please feel free to let me know.

    Very strange! It is worth mentioning that I only get the warnings when I click one of the main navigation bars, then one of the filters.

    For example; click Supply, then Home (no warnings), then Filter 2 (warnings spam).

    If anyone else is able to trigger the warnings by clicking Supply, Home, then the Filters, please let me know what versions you're running!

    Thanks,
    Ryan

    I ended up requesting support with Qt Enterprise and they gave instructions on how to fix it.

    For anyone else having this issue, I had to setGraphicsEffect to nullptr after the animation has finished: "ui->buttonItem10->setGraphicsEffect(nullptr);".

    connect(animationFadeIn7,&QPropertyAnimation::finished,[=](){effectFadeOut7->deleteLater(); ui->buttonItem10->setVisible(0); ui->buttonItem10->setGraphicsEffect(nullptr); });
