我正在写一个C++ Qt应用程序,占用整个屏幕的主窗口和包含模拟控件的子窗口。Qt5.6 RHEL全屏应用程序窗口和子窗口
我使用RHEL 7.2和Qt 5.6。问题在于子窗口虽然在任务列表中可见,但在显示屏上不可见。从模拟窗口
clsMainWin::clsMainWin(QRect rctScr, QWidget *parent) : QMainWindow(parent)
,ui(new Ui::clsMainWin) {
ui->setupUi(this);
//Set-up window container background and size
setWindowFlags(Qt::Window | Qt::FramelessWindowHint);
setWindowIcon(QPixmap(1,1)));
setGeometry(rctScr);
//Display the window container
showFullScreen();
#ifdef SIM_WINDOW
mpobjSimWin = NULL;
#endif
}
void clsMainWin::paintEvent(QPaintEvent* pEvt) {
//Prevent compiler warning!
pEvt = pEvt;
//Get painter context
QPainter objPainter(this);
//Fill the root area with the chosen colour
objPainter.fillRect(geometry(),
QColor(mpobjRoot->strGetAttr(mcszXMLattrColorBg)));
#ifdef SIM_WINDOW
if (mpobjSimWin == NULL) {
mpobjSimWin = new clsSimWin(this);
mpobjSimWin->setWindowState((windowState() & ~Qt::WindowMinimized) | Qt::WindowActive);
mpobjSimWin->raise(); // for MacOS
mpobjSimWin->activateWindow(); // for Windows
}
#endif
}
构造函数片段:
clsSimWin::clsSimWin(QWidget *parent) : QDialog(parent)
,ui(new Ui::clsSimWin) {
assert(parent != NULL);
ui->setupUi(this);
//Set the window title
this->setStyleSheet("background-color: white;");
setWindowTitle("Data simulator");
//Set-up window
Qt::WindowFlags flags = (Qt::Window
| Qt::WindowTitleHint
| Qt::CustomizeWindowHint)
& ~Qt::WindowMaximizeButtonHint;
setWindowFlags(flags);
setFixedSize(mcintWindowWidth, mcintWindowHeight);
//Display the window
show();
}
这还不是全部的代码,但希望足以显示这个问题可能是我做了什么,在哪里?
