General and Desktop

Sorry, you just cut the actual error message. You must not change the ui_xxx.h files manually, as they are regenerated by uic for certain reasons. If you move out your own class definition into another header file, make sure you #include that file where you included the ui_xxx.h file have "include guards":http://en.wikipedia.org/wiki/Include_guard in that file and make sure they are different from the other one!

As already discussed in "this older thread":http://developer.qt.nokia.com/forums/viewthread/2144, there is no really good, out-of-the-box solution for this. You'll have to find your own workaround for that issue, sorry.

I have QListWidget with 4 items inside. e.g., group1 group2 group3 group4 I can edit these items by pressing F2 button from the keyboard by placing the cursor on anyone of these items let say , if i try to change the 4th item from "group4" to "group1". My application will throw some error like "Name 'group1' already exist in this list" @ //i am getting the message using the following code QMessageBox msg; msg.setText(QString("Name").append(strName).append(" already exists in this list")); msg.exec(); emit editgroup(); // the corresponding SLOT is editlist() @ after throwing this error message , i want to have the same item as editable as i had before ..like when i press the F2 button from the keyboard....BUT ITS NOT OCCURING... :-( Even i am calling the SLOT editlist from the SIGNAL editgroup() ..after getting this messagebox @ connect( this, SIGNAL(editgroup()), this SLOT(editlist()); @ @ // this is the slot function. void testDlg::editList() { QListWidgetItem *item = ui->listWidget->currentItem(); item->setFlags( item->flags() | Qt::ItemIsEditable ); ui->listWidget->editItem( item ); } @

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.
