[Qt-interest] Setting custom properties with style sheets.

[Roland Labrecque]

I would like to set custom properties from a style sheet. I can 
successfully query a custom property but can't set it. Is this even 
possible?

I've included an example below which defines a property "columns" on 
LineEditField.

My style sheet looks like:

LineEditField[columns="10"] { background-color: green; }  /* This Works: 
ie the background on all LineEdits with the "column" property are green */
LineEditField#le2 { columns: 15; }   /* This doesn't do anything and 
reports an error on the command line "Unknown property columns" */
 

Do I have the syntax wrong or is this just not possible.

Cheers,
Roland



Example Code:
 >>----------------------------------------------------------------------------------------------------

#include <QtGui>
#include <QDebug>

class LineEditField : public QLineEdit
{
Q_OBJECT

    Q_PROPERTY(int columns
               READ get_columns
               WRITE set_columns
               STORED true)
public:
    LineEditField(QWidget * p=0) : QLineEdit(p) {set_columns(0);}
    int get_columns() { return m_c; }
    
public slots:

    void set_columns(int c)
    {
      m_c=c;
      setText(QString().setNum(m_c));
      qDebug() << "set_columns(" << c << ")";
    }

private:
  int m_c;

};


int main(int argc, char *argv[])
{
QApplication a(argc, argv);


LineEditField* le1 = new LineEditField;
le1->setObjectName("le1");
le1->setProperty("columns",QVariant(10));

LineEditField* le2 = new LineEditField;
le2->setObjectName("le2");
le2->setProperty("columns",QVariant(20));

QVBoxLayout* vl = new QVBoxLayout;
vl->addWidget(le1);
vl->addWidget(le2);
QWidget* w= new QWidget;
w->setLayout(vl);


a.setStyleSheet(
    "LineEditField[columns=\"10\"] { background-color: green; }"
    "LineEditField#le2 { columns: 15; }"
    );

w->show();

a.exec();

}
