qmainwindow

So, I'm using Python and PyQt. I have a Main Window that contains a QTableWidget, and a dialog that opens modally and has some QLineEdit widgets... All right so far, but I have 2 problems: When the dialog opens, my Main Window freezes, and I don't really like that... What I want, when I finish editing a QLineEdit, is that the program will search the QTableWidget, and if the text from the QLineEdit exists in the table, a dialog will come up and informe about that. That's the general idea. But, so far, I seem to only be able to create a new QTableWidget instance, and I can't use the data from

I am using QMainWindow for GUI development of my project..One problem I am Stuck with is blocking all other visible windows from getting input, while one is in operation. I can not use QDialog.Because rich features of QMainWindow is required. How can I declare a particular window as modal? I tried with QWidget::setWindowMOdality() . Here is a demo program, what I tried but it didnt work. #include <QApplication> #include <QMainWindow> #include <QPushButton> int main(int argc, char **argv){ QApplication a(argc, argv); QMainWindow *w1 = new QMainWindow(); w1->resize(500,800); w1->move(100,50); w1

I have a number of QDockWidgets , all docked in a single QMainWindow . I have overridden the showEvent , and after passing the event on to the base class I am restoring the dock widget's geometry void DockWidget::showEvent(QShowEvent* ev) { QDockWidget::showEvent(ev); QByteArray byte_array = settings_.value(id + ".geometry").toByteArray(); LOG("rest: %s", QString(byte_array.toHex())); QDockWidget::restoreGeometry(byte_array); } In my QMainWindow::closeEvent I am calling saveSettings for each of my dock widgets void MainWindow::closeEvent(QCloseEvent* ev) { QList<DockWidget*> dock_widgets =

I have a few widgets in a main window. i want the user to be able to resize the widgets inside the window as they please, just like how one would resize the main window. Do I have to make a layout container to enable this? or ....layout? Buh the layout contains are static once the window is rendered. In the picture the three widgets should be enable with resizing such that the user can drag their sides/corners to expand or minimize the widget size. One thing you could do is to use some QSplitter 's though it isn't directly as nuanced as you pointed out. Have a look at the image (you can drag

I’m trying to make an application consisting of a QMainWindow , the central widget of which is a QToolBar (it may not be usual, but for my purpose the toolbar’s well suited). Docks are allowed below only. I added a QDockWidget to it, and a QAction on the QToolBar toggles the QDockWidget on and off with removeDockWidget() and restoreDockWidget() . The default size of the QMainWindow is 800 by 24, QToolBar ’s maximumHeight is set to 24 too. Right after the removeDockWidget() is called, QMainWindow ’s geometry is set back to (0,0,800,24) with setGeometry() . What I want to achieve is to resize
