<![CDATA[[SOLVED =)]ComboBox Qstring but need an int or GLenumb]]>Hey everyone once again I got a question to ask,

I got a combobox with 10 values:
"Picture of the combobox values here":http://i.imgur.com/lYo9A.jpg

As you can see it's a list of OpenGL primitives that are GLenumb.

I got this function:
@void MainWindow::on_cmbx_primatives_currentIndexChanged(const QString &arg1)
{
GLFrame->RenderThread.setPrimitiveType(arg1);
primL = arg1;
}@

This sets the PrimitiveType value in the rendering class but clearly it's just a string and not an integer. Is it possible to set an additional value to a comboxbox argument for example the Text would be as an additional value that I could pass???
"Since you can set comments and other additional values":http://i.imgur.com/jYYrB.jpg

@GL_POINTS : but contain 0x0000@

thank you

Sounds pretty like that....

Well I removed all the values from the comboxbox in the Qt creator interface and the program crashed.
"The program has unexpectedly finished."

So then I just randomly added an item to the combo box and it worked again. Why's that?

should be enough... or:

@QString arg1 = ui->cmbx_primatives->currentText();@
it will return text of currently selected item

I tried @QString arg1 = ui->cmbx_primatives->itemText(index).toStdWString();@ but that's wrong

@void currentIndexChanged ( int index )@
signal instead one with QString.

your slot will be when like this:
@void MainWindow::on_cmbx_primatives_currentIndexChanged(int index)
{
primL = ui->cmbx_primatives->itemData(index).toInt();
GLFrame->RenderThread.setPrimitiveType(primL);
}@

but how do I access the integer value from arg1 so I could pass it to the render class?

@ui->cmbx_primatives->addItem(const QString("Test"), const QVariant & userdata = QVariant(const int(0x0000)));@

@void void QComboBox::addItem ( const QString & text, const QVariant & userData = QVariant() )@

userData can be all you want...
