SubClass QFileIconProvider (from QDirModel) not compile....

[patrik08]

QFileIconProvider is not a QObject, so you can't use Q_OBJECT with it.

if i remove Q_OBJECT can compile but not running...! and not display my icons..

i put Q_OBJECT why? on scribus apps having....

http://stuff.mit.edu/afs/athena/soft...ustomfdialog.h

maybe is qt3 ... i dont no..

#include "scribusapi.h"
 
/**
  *@author Franz Schmid
  */
class SCRIBUS_API ImIconProvider : public QFileIconProvider
{
    Q_OBJECT
    QStringList fmts;
    QPixmap imagepm;
    QPixmap docpm;
    QPixmap pspm;
    QPixmap pdfpm;

#include "scribusapi.h"

/**
  *@author Franz Schmid
  */
class SCRIBUS_API ImIconProvider : public QFileIconProvider
{
    Q_OBJECT
    QStringList fmts;
    QPixmap imagepm;
    QPixmap docpm;
    QPixmap pspm;
    QPixmap pdfpm;

To copy to clipboard, switch view to plain text mode 

i put so... and default icon is here ...

modeluser = new QDirModel();
modeluser->setIconProvider(new ImIconProvider());
modeluser->setResolveSymlinks(false);
usertree->setModel(modeluser);
modeluser->setSupportedDragActions(Qt::CopyAction);
usertree->setDragEnabled(true);
usertree->setRootIndex(modeluser->index(ustart));

i can drag file direct to desktop (on model or outsite model) or viceversa .. is running rename delete , open file on clicked all running .. only the icon is fake....

QFileDialog display correct all icon (QDirModel NO!) .... so if you take QFileIconProvider from QFileDialog

and done to model this is not running ... i suppose a BUG!

#include <QtGui>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QDirModel model;
    model.setIconProvider(QFileDialog::iconProvider());
    QTreeView tree;
    tree.setModel(&model);
    tree.setWindowTitle(QObject::tr("Dir View"));
    tree.resize(640, 480);
    tree.show();
 
    return app.exec();
}

#include <QtGui>

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

    QDirModel model;
    model.setIconProvider(QFileDialog::iconProvider());
    QTreeView tree;
    tree.setModel(&model);
    tree.setWindowTitle(QObject::tr("Dir View"));
    tree.resize(640, 480);
    tree.show();

    return app.exec();
}
