QT combobox with multiple items at the same line - c++

Question

The buttonbox above has multiple items on the same line. It's a program called draftsight, written in QT.
The buttonbox with the red square is what i have, but i need more info on the same line..
Someone know's how to achieve this??
My current code to add 2 items in the same combobox line :
//setup combobox :
QComboBox *colors = new QComboBox;
ui->toolBar_color->addWidget(colors);
colors->setMinimumWidth(150);
//routine to fill the combobox with external data :
colors->clear();
Dialog_color().extern_toolbar_load();
QPixmap pixmap(15,15);
for(int i = 0; i<red_list.size(); i++){
pixmap.fill(QColor (red_list.at(i),green_list.at(i),blue_list.at(i)));
colors->addItem(pixmap, comments.at(i));
}
So in fact i need something like this :
colors->addItem(pixmap, pixmap, pixmap, "text", "text");
Is there a way?

Answer 1

thanks for your response,
To explain the red_list, green_list, blue list. This are the rgb color value's that user has set up in a tablewidget. The tablewidget data is loaded during program start and during program execution if refreshes from a text file which stores the user defined values. The dialog is not finished, but it's working as expected.
I have been thinking also about combining several pixmap to a long pixmap, but it must be a automated way to combine all rgb value's and other value's like linetype etc which each other. So how can i automate combining several pixmap's to one.. Hmm i have to think about this.
How did they do this in draftsight with QT designer? Default Systems will not provide the solution i think.
All input is welcome !
Edit, i found a solution.. Which can combine things automated when the function example is expanded. So far i am satisfied with the solution.
If qt can do a update for this. That would be nice. For the combobox a pressed signal would be nice also instead of using a event filter..
//setup combobox..
QComboBox *test = new QComboBox;
ui->toolBar_layer->addWidget(test);
test->setMinimumWidth(150);
test->setMinimumHeight(20);
test->addItem("test item");
test->setIconSize(QSize(100, 15));
//setup picture template..
QPixmap pixmap(100, 15);
pixmap.fill(Qt::transparent);
QPainter painter(&pixmap);
//contruct a picture based on rgb colors..
QPixmap pixmap_1(15,15);
pixmap_1.fill(QColor (255,0,0));
painter.drawPixmap(0, 0, 15, 15, pixmap_1);
//load pictures from file..
painter.drawPixmap(30, 0, 15, 15, QPixmap(":/icons/edit-paste.svg"));
painter.drawPixmap(60, 0, 15, 15, QPixmap(":/icons/terminal.svg"));
painter.end();
test->addItem(pixmap, "combobox");
