General and Desktop

Thanks for your valuable inputs.. DSav.. Its working fine...

But there are restirictions to the windows flags. Like if you want to have a system menu on windows, you (AFAIK) automatically get a close button. AFAIK you can change that on windows by reimplementing WM_NCXXX messages in the winEvent function of a widget...

[quote author="task_struct" date="1314781082"]@Cpowa, as I understand from Andres answer QGraphicsPolygonItem has a bounding rectangle and 0,0 is at its lower right corner. [/quote] Then you misunderstood my post. My point was, that (0,0) is not a fixed point for any item. It is just the origin of the coordinate system, but because you are allowed to use negative coordinates, the actual drawing of the item could happen anywhere relative to this point. You can make (0,0) the upper left or the lower right corner of your item, but you can also make it the center, or draw you item so that (0,0) is completely outside your item. Bottom line: (0,0) can be anywhere. It is another question whether it should, of course.

You can track the status of the bug "here":https://bugreports.qt.nokia.com/browse/QTBUG-8453.

Indeed, it should work. This snippet perfectly works for me : @ QTableWidget *table = new QTableWidget(2, 3, this); Q_ASSERT(table->rowCount() == 2); table->removeRow(1); Q_ASSERT(table->rowCount() == 1); @

Be sure and edit the post title to add [Solved].

[quote author="Cayan" date="1314734115"]Which executable is not working then? This should be happening from a different executable that had been generated before.[/quote] My class in Qt Creator is called Wave. I have two files: "Wave" and "Wave-build-desktop". "Wave-build-desktop" was generated by Qt and the executable file called Wave.exe is in there. When i click on Wave.exe to open it, it opens the application window, but none of the push button are working and no items are displayed in the comboboxes. But when i navigate to this file in terminal and execute it from there, the application window pops up and everything works ok.

You do know that you don't have to put save and read code together, right? Volker's examples (settings and getting) were meant to be put in separate places in the code, not called one right before the other...

Yes, thanks guys. Thanks mlong. I used QSettings. Solution: @void wave::on_addboardButton_clicked() { QMap<QString,double> map; QSettings settings("/home/test/Documents/Wave/signalgenerator.ini", QSettings::IniFormat ); settings.beginGroup( "values" ); foreach( QString childKey, settings.childKeys() ){ if (childKey.toInt() == ui->comboBox->currentIndex()+1) { int i = ui->comboBox->count(); i += childKey.toInt(); map[ QString::number(i) ] = ui->newCalNumberAdd->text().toDouble(); ui->comboBox->addItem("Board"+QString::number(i)); } QMapIterator<QString,double> it(map); while( it.hasNext() ){ it.next(); settings.setValue( it.key(), it.value() ); } } settings.endGroup(); }@

Many thanks! I think that this is sufficient.

I'm not that font expert but does a font embedded in the applications resources and "QFontDatabase::addApplicationFont()":http://doc.qt.nokia.com/latest/qfontdatabase.html#addApplicationFont not work?

Problem is this code snippet: @     listButtons[grid_button]->setMinimumSize(QSize(grid_button_width, grid_button_height));     listButtons[grid_button]->setMaximumSize(QSize(grid_button_width, grid_button_height));     listButtons[grid_button]->setBaseSize(QSize(grid_button_width, grid_button_height)); @ The sizes of buttons and the spacing of layouts differ from platform to platform. You do set a fixed size, which will clash with the platform defaults.

... and what if I try: @ GestoreComunicazioneSatellite::~GestoreComunicazioneSatellite() { m_thread->exit(123); m_thread->deleteLater(); } @ ?

Yes, a delegate is definitely what you want. Subclass QStyledItemDelegate and do your custom painting there.

I have merged your two topics into one.

And remember that a slot is a normal C++ function (member function). Therefore you can perform any action in your slot. For your example, it will give : @ void MyClass::onMyButtonClicked() { myLabel->setText(myLineEdit->text()); } @ And btw, welcome and have fun with Qt :)
