Qt 透明小部件

只是一个简单的问题。

我目前正在使用 Qt 构建我的应用程序界面。 我为主页设置了背景图像,并使用 stackedWIdgets 从一个窗口滑动到另一个窗口。

setStyleSheet("background-image: url(:/spherebackground.png);"
                        "background-repeat: no-repeat;"
                        "background-position: center center");

当应用程序启动时,会出现一个由 3 种布局组成的页面:

1) 一个包含带有 QPushButtons 的 topToolbar Widget 和一个显示 PageTitle 的标签 2) 中间是一个包含 SlidingStackedWidgets 的 mainPageLayout 3)BottomToolBar

mainFrameWidget包含一个mainFrameLayout:

mainPageWidget=new QWidget();

mainPageLayout=new QVBoxLayout();

//I add the buttons and others
mainPageLayout->addWidget(addEntryButton);
mainPageLayout->addWidget(vocaButton);
mainPageLayout->addWidget(exprButton);
mainPageLayout->addWidget(rulesButton);
mainPageLayout->addWidget(learnButton); 

mainPageWidget->setLayout(mainPageLayout);

然后,我使用设计器创建了其他页面

然后将页面添加到滑动堆栈的函数

 void MainWindow::createSlidingStackedWidget() {
 //the slidingStacked is the Widget that contains the subslidingWidgets

 slidingStacked= new SlidingStackedWidget(this);
 slidingStacked->addWidget(mainPageWidget);
 quickAddView = new QuickAddController(); //which is a UI widget
 slidingStacked->addWidget(quickAddView);

 }

然后,当按下 mainLayout 中的按钮时,它会触发这样的函数

void MainWindow::slideInAdd(){
topToolBar->clear();
slidingStacked->setVerticalMode(true);
slidingStacked->slideInIdx(1);
setupTopToolBar("Terminer","Ajout Entrée","Modifier");
bottomToolBar->hide();
QObject::connect(goBackButton,SIGNAL(clicked()),this,SLOT(backFromAdd()));
}

事情是我正在尝试移植我为 iPhone 创建的一个应用程序,我希望它具有相同的“外观和感觉”,但是当我从一个页面滑动到另一个页面时......

1)动画闪烁 2)我希望滑动小部件除了控件之外都是透明的(QPushButtons ...) 但它们具有与我在代码开头设置的相同的球体背景 3)当我希望它们成为标准时,我的标签和控件也具有相同的背景图像 (例如:标签应该有白色背景)

我不明白为什么......

希望这能让你更好地了解正在发生的事情......

Just a quick question.

I'm building my app interface at the moment with Qt.
I set a background image for the mainpage and I use stackedWIdgets to slide from one window to another.

setStyleSheet("background-image: url(:/spherebackground.png);"
                        "background-repeat: no-repeat;"
                        "background-position: center center");

When the application starts, a page appears which is made of 3 layouts:

1) One that contains a topToolbar Widget with QPushButtons, and a label displaying the PageTitle
2) in the middle, a mainPageLayout that contains the SlidingStackedWidgets
3) the BottomToolBar

The mainFrameWidget contains a mainFrameLayout:

mainPageWidget=new QWidget();

mainPageLayout=new QVBoxLayout();

//I add the buttons and others
mainPageLayout->addWidget(addEntryButton);
mainPageLayout->addWidget(vocaButton);
mainPageLayout->addWidget(exprButton);
mainPageLayout->addWidget(rulesButton);
mainPageLayout->addWidget(learnButton); 

mainPageWidget->setLayout(mainPageLayout);

Then, I have the other pages created with the designer

And then a function that add the pages to the slidingStacked

 void MainWindow::createSlidingStackedWidget() {
 //the slidingStacked is the Widget that contains the subslidingWidgets

 slidingStacked= new SlidingStackedWidget(this);
 slidingStacked->addWidget(mainPageWidget);
 quickAddView = new QuickAddController(); //which is a UI widget
 slidingStacked->addWidget(quickAddView);

 }

And then, when a button in the mainLayout is pressed, it triggers a function like this

void MainWindow::slideInAdd(){
topToolBar->clear();
slidingStacked->setVerticalMode(true);
slidingStacked->slideInIdx(1);
setupTopToolBar("Terminer","Ajout Entrée","Modifier");
bottomToolBar->hide();
QObject::connect(goBackButton,SIGNAL(clicked()),this,SLOT(backFromAdd()));
}

The thing is that I'm trying to port an application I created for the IPhone and I want it to have the same "Look and Feel" but when I slide from one page to another...

1) the animation flickers
2) I would like the sliding widgets to be transparent except for the controls (QPushButtons...)
but they have the same sphere background as the one I set up at the beginning of the code
3) My labels and controls also have the same background image when I would like them to be standard
(eg : a label should have a white background)

I can't figure out why...

Hope this will give you a better idea of what's going on...

就 2) 和 3) 而言,这是因为小部件默认继承其父级的调色板。要解决此问题,您可以显式设置它们的样式,或者在创建它们后将其调色板指定为默认应用程序调色板。我不知道如何处理第一个问题。

So far as 2) and 3) go, that is because widgets inherit their parent's palette by default. To fix this, you can explicitly style them, or assign their palette to be the default application palette after they are created. I don't know how to handle the first problem.
