Why i can not subclass QFileIconProvider

waht is mistake? on qt_metacast moc error moc exist.....

i append setIconProvider

modeluser->setIconProvider(pcsis);


modellocal->setResolveSymlinks(false);
modeluser->setResolveSymlinks(false);
usertree->setModel(modeluser);
mlocal->setModel(modellocal);

try running moc on your Header file and include it in your project...

try running moc on your Header file and include it in your project...
ex:


moc your_Header.h -o moc_your_Header.cpp

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

[aamer4yu]

oh ho.... didnt think of that :(

[viking]

QFileIconProvider is not a QObject, so you can't use Q_OBJECT with it.
hi wysota, could you elaborate?

[aamer4yu]

Q_OBJECT can be used with those classes which are derived from QObject at any level.

as QFileIconProvider is not derived from QObject, it cannot be used with Q_OBJECT.

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/software/scribus_v1.3/include/scribus/customfdialog.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;





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();
}
