    When I assign a button or label for the application, I can get output on the target device, but when I change color, it does not give any output. Do you have an idea about it?

      @Buket said in Set Palette or stylesheet causing my application did not works properly.:

      No, you do not provide enough information.
      "When I assign a button or label for the application" - what does that mean?
      "but when I change color" - color of what? And how do you change color?
      What device?
      What Qt version?

        The device I am working on is ARM-based (Rockchip RK3288, ARM Cortex-A17 CPU, Mali-T760 MP4 (T764) GPU) motherboard.
        Qt version: 5.12.2

        When I change the color of the button or the color of the label I added using the palette, I cannot get the standard output I get on the target device.
        When I debug without using color, I can get output.

            .pro file :

            QT       += core gui
            
            greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
            
            CONFIG += c++11
            
            # The following define makes your compiler emit warnings if you use
            # any Qt feature that has been marked deprecated (the exact warnings
            # depend on your compiler). Please consult the documentation of the
            # deprecated API in order to know how to port your code away from it.
            DEFINES += QT_DEPRECATED_WARNINGS
            
            # You can also make your code fail to compile if it uses deprecated APIs.
            # In order to do so, uncomment the following line.
            # You can also select to disable deprecated APIs only up to a certain version of Qt.
            #DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000    # disables all the APIs deprecated before Qt 6.0.0
            
            SOURCES += \
                main.cpp \
                mainwindow.cpp
            
            HEADERS += \
                mainwindow.h
            
            FORMS += \
                mainwindow.ui
            
            # Default rules for deployment.
            #qnx: target.path = /tmp/$${TARGET}/bin
            #else: unix:!android: target.path = /opt/$${TARGET}/bin
            #!isEmpty(target.path): INSTALLS += target
            target.path = /usr/local/foto
            INSTALLS += target
            
            RESOURCES += \
                kaynakca.qrc
            

            .ui background image code (I add stylesheet for toolbutton):

            background-image: url(:/new/prefix1/deneme.jpg);
            

            .qrc file (resource):

            <RCC>
                <qresource prefix="/new/prefix1">
                    <file>deneme.jpg</file>
                </qresource>
            </RCC>
            

            I managed to add color. I can only change the button color when I add the stylesheet as RGB.

            background-color:rgb(138, 226, 52)
            

            I still can't see the target device when I add .png file and deploy. Only the standard button appears.

            Edit:
            I tried deploying using Label and Pixmap but the result did not change.
