如何在带有样式表的QWizard中删除水平线? [英] How to remove the horizontal line in a QWizard with a stylesheet?
问题描述
我正在处理QWizard
的样式表,我想删除按钮上方的水平线.
I am working on stylesheet of a QWizard
and I would like to remove the horizontal line just above the push button.
我已经在此处发布了一个最小示例,该问题已由scopchanov从最小示例中解决,但是我在我的项目中有一些代码行避免了解决方案的工作,所以我在这里发布了另一个问题.
I've already posted a minimal example here, the question was solved by scopchanov from the minimal example, but I have some lines of code in my project that avoids the solution to work, so I post another question here.
这是我的代码(完整的可构建示例可以从要旨中下载在这里 ):
Here is my code (the complete buildable example can be downloaded from the gist here):
licensewizard.h
#include <QWizard>
class LicenseWizard : public QWizard {
Q_OBJECT
public:
LicenseWizard(QWidget *parent = 0);
};
licensewizard.cpp
#include <QApplication>
#include <QtWidgets>
#include "licensewizard.h"
LicenseWizard::LicenseWizard(QWidget *parent) : QWizard(parent) {
setWizardStyle(ModernStyle);
// solution from @scopchanov https://stackoverflow.com/a/52541248/8570451
QPalette p(palette());
p.setColor(QPalette::Mid, p.color(QPalette::Base));
setPalette(p);
}
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
// this line breaks @scopchanov solution.
// replace QLabel by QPushButton, or anything else... still broken.
qApp->setStyleSheet("QLabel { color:black; }");
LicenseWizard wizard;
wizard.show();
return app.exec();
}
正如scopchanov所说,我使用了QPalette
技巧.但是我在qApp上定义了一个很大的样式表,这就是造成我问题的原因.使用很小的样式会遇到相同的问题.
As scopchanov said, I used the QPalette
trick. But I have a big style sheet defined on the qApp and this is the cause of my problem. Using a very small style give the same problem.
要重现的步骤是在QApplication
声明之后添加以下行:
The step to reproduce is to add this line after the declaration of the QApplication
:
qApp->setStyleSheet("QLabel { color:black; }");
我希望有人能帮助我.
推荐答案
要解决此问题,请设置整个应用程序的调色板,而不仅仅是LicenseWizard
类,如下所示:
To fix this, set the palette of the whole application, instead of just the LicenseWizard
class, like this:
LicenseWizard::LicenseWizard(QWidget *parent) : QWizard(parent) {
setWizardStyle(ModernStyle);
}
int main(int argc, char *argv[]) {
QApplication app(argc, argv);
QPalette p(qApp->palette());
p.setColor(QPalette::Mid, p.color(QPalette::Base));
qApp->setPalette(p);
qApp->setStyleSheet("QLabel { color:black; }");
LicenseWizard wizard;
wizard.show();
return app.exec();
}
注意:如我对链接问题的回答中所述,如果此颜色角色由其他任何项目使用,则其颜色也会受到影响.
Note: As mentioned in my answer to the linked question, if this color role is used by any other item, its color would be affected as well.
