Using Qt 4.8.4 on Windows 7 (MSVC 2010) I have a standard QMainWindow in my app with toolbar and menu. I want to achieve that toolbar and menu keep their grey color, but the central widget should have a white background. My test case is an app with just one label in the central widget. In order to see the problem, add or remove the Q_OBJECT line in test.h
When Q_OBJECT is there, only the label gets a white bg. If Q_OBJECT is commented out, the whole central widget is white. Of course, I want the whole area white, but also need Q_OBJECT.
Here’s the files:
main.cpp:
#include "test.h"
class testwin : public QMainWindow {
public:
QWidget *centralWidget;
QToolBar *mainToolBar;
testwin(QWidget *parent = 0) : QMainWindow(parent) {
centralWidget = new test(this);
setCentralWidget(centralWidget);
mainToolBar = new QToolBar(this);
this->addToolBar(Qt::TopToolBarArea, mainToolBar);
};
~testwin() {};
};
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
testwin w;
w.centralWidget->setStyleSheet("background-color: white;");
w.show();
return a.exec();
}
test.h:
#ifndef TEST_H
#define TEST_H
#include <QtGui>
class test : public QWidget
{
Q_OBJECT // remove this
public:
QLabel *label;
test(QWidget *parent = 0) {
resize(400, 300);
label = new QLabel(this);
label->setText("Test");
};
};
#endif // TEST_H
