QSizeGrip is not visibile inside the QRubberBand when compiled on OSX.

[SGaist]

Hi,

I may be wrong but IIRC, on OS X there's no visible size grip thus QSizeGrip follows that.

[CarLoowwww]

So if you were right, is there any alternative to risize the QRubberband?

[mrjj]

so besides not showing it, it cannot resize ? Nothing happens if u drag where QSizeGrip should have been drawn?

[CarLoowwww]

@mrjj yes, draging the QRubberBand is the only thing that i can do. I cannot resize it since the QSizeGrip is not shown. Do you have any idea or alternative to this issue?

[mrjj]

@CarLoowwww
So the QSizeGrip you create , are disabled by Osx??
I thought it was merely a visual thing and they are drawn differently but you say they are completely removed?

[CarLoowwww]

@mrjj yes, i took some research about QSizeGrip, and they completely removed it on OSX platform. So im looking on a way to resize the QRubberBand when i drag it on its corner.

@CarLoowwww
Well you can maybe reuse some code from here

Can you provide a complete sample code of your widget using QRubberBand ?

That will make it more easy to reproduce your use case.

@SGaist

ok here is the custom class of my QRubberBand.

#include <QSizeGrip>
#include <QMouseEvent>
#include <QHBoxLayout>
#include <QGraphicsColorizeEffect>


RubberBandCustomized::RubberBandCustomized(QWidget *parent) : QWidget(parent)
{
    //here is buliding rubber band
      QHBoxLayout* layout = new QHBoxLayout(this);
      layout->setContentsMargins(0, 0, 0, 0);

      QSizeGrip* grip1 = new QSizeGrip(this);
      QSizeGrip* grip2 = new QSizeGrip(this);

      layout->addWidget(grip1, 0, Qt::AlignLeft | Qt::AlignTop);
      layout->addWidget(grip2, 0, Qt::AlignRight | Qt::AlignBottom);

      this->resize(100,100);


      rubberband = new QRubberBand(QRubberBand::Rectangle, this);
      
      QGraphicsColorizeEffect *ee = new QGraphicsColorizeEffect(rubberband);
      ee->setColor(QColor(0,0,0,0));
      rubberband->setGraphicsEffect(ee);

      rubberband->show();
}
void RubberBandCustomized::resizeEvent(QResizeEvent *e)
{

    rubberband->resize(e->size());

}

and here is the code where i create my Custom Rubberband.

PhotoBoardPlugin_Dialog::PhotoBoardPlugin_Dialog(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::PhotoBoardPlugin_Dialog)
{
    ui->setupUi(this);

    scene = new QGraphicsScene(this);
    ui->graphicsView->setScene(scene);
    ui->graphicsView->setStyleSheet( "QGraphicsView { border-style: none; }" );
    ui->graphicsView->setStyleSheet( "QGraphicsView { background-color: rgb(0,0,0); }" );

    //setting size to fit scene
    int scene_w = ui->graphicsView->width();
    int scene_h = ui->graphicsView->height();

    sourceImage = QImage(QString("://textureForTest/mardana_330x468.png"));
    sourceImage = sourceImage.scaled(QSize(scene_w,scene_h),Qt::KeepAspectRatio);
    m =  QPixmap::fromImage(sourceImage);
#ifdef Q_OS_MACX
    setWindowIcon(QIcon(""));
    ui->pushButton_2->setDefault(true);
#endif

    int wc = ( scene_w - m.width())/2;
    int hc = ( scene_h - m.height())/2;

    pixmap = scene->addPixmap(m);
    pixmap->setPos(wc,hc);
    //pixmap->setFlag(QGraphicsItem::ItemIsMovable);  

    rubberBand = new RubberBandCustomized(ui->graphicsView);
    rubberBand->move(150, 150);

    setWindowTitle(tr("Plugin - Photo Board"));

}

Inside the whitebox there should be 2 QSizeGrip, but since it is not shown i am not able to resize the white box which is the QRubberBand that uses a QWidget with SubWindow Flag.

[SGaist]

Your code can't be compiled, there are missing functions.

[CarLoowwww]

@SGaist Edited codes. I removed some function, since those function are just to make sure that the rubberband will not be moved beyond the border of the photo.

I also tried this sample Link to sample and compile it in two different platform(Using Windows and OSX). The Windows can freely resize the rubberband and working very well. While when i compiled it on OSX the initialization of the position and size of the rubberband are working but it has no resize handle/no interaction.
