Widgets within a QGraphicsScene are blank
-
I'm trying to add a QgraphicsView(QColorDialog) widget onto a Palette dialog, but the QGraphicsscene corresponding to the QColorDialog widget is always blank and it would be of great help if readers could help me correct my mistake
Qt-4.8.4-Linux(CentOS)
- The GraphicsView widget which will be included in the Pallette Dialog
@ClrWidget::ClrWidget(QWidget *parent) :
QGraphicsView(parent)
{
setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
setFrameStyle(QFrame::NoFrame);
setScene(new QGraphicsScene(this));
_dialog = new QColorDialog();
_dialog->setOption(QColorDialog::NoButtons, true);
setMinimumSize(_dialog->size());
setMaximumSize(_dialog->size());QGraphicsProxyWidget *proxyWidget = new QGraphicsProxyWidget();
proxyWidget->setWidget(_dialog);
//scene()->addItem(proxyWidget);
//scene()->setSceneRect(proxyWidget->geometry());scene()->addWidget(_dialog);
scene()->setSceneRect(_dialog->geometry());
}@- Palette Dialog Constructor
@
PaletteDialog::PaletteDialog(QWidget *parent)
: QDialog(parent),
ui(new Ui::PaletteDialog),
{
//PaletteDialog sets up the ClrWidget
ui->setupUi(this);
...
}@

Hi,
in your code you don't use ClrWidget.
Is QColorWidget a Qt class?

Hi mcosta,
I probably wasn't clear in my earlier posting, probably being a new user shows up. I've edited my earlier post and below is some more detail.ClrWidget is essentially a QColorDialog and I'm using this custom widget(promoted from QWidget to ClrWidget) within a Pallette Creator(PC) dialog(defined as PC.ui )
Within PC.cpp,
@PCDlg::PCDlg(QWidget* parent) : QDialog(parent) :
QDialog(parent)
, ui(new Ui::PCDlg),
, d(new PCDlg(this))
{
ui->setupUi(this);
@I'm not able to understand why the custom widget(ClrWidget) does not show up within the PC dialog.
I'm using Qt-4.8.4 on Linux
