How do show in a QFileDialog all files except the executable files?

**bhodi78** · 27th April 2010, 11:20

The only way I can think of is to make a list, but this way I have to anticipate all possible types of files, that is not possible.

Qt Code:

Switch view

QFileDialog dialog(this);
dialog.setFileMode(QFileDialog::ExistingFile);
dialog.setNameFilter(tr("All files except .exe (*.png *.xpm *.jpg *.pdf *.gif ............infinite extensions..........)"));

QFileDialog dialog(this);
dialog.setFileMode(QFileDialog::ExistingFile);
dialog.setNameFilter(tr("All files except .exe (*.png *.xpm *.jpg *.pdf *.gif ............infinite extensions..........)"));

To copy to clipboard, switch view to plain text mode

Anyone has a better idea?
Thank you very much.

Just use QDialog::setFilter not QDialog::setNameFilter

Sorry, I tried as you say, but does not work.

Qt Code:

Switch view

#include <QApplication>
#include <QFileDialog>
 
int main( int argc, char **argv ) {
 
  QApplication app( argc, argv );
  QFileDialog dialog(0);
  dialog.setFileMode(QFileDialog::ExistingFile);
  dialog.setFilter(QDir::Files);  //<--------------------------All files except executable files.???
  dialog.exec();
  return 0;
}

#include <QApplication>
#include <QFileDialog>

int main( int argc, char **argv ) {

  QApplication app( argc, argv );
  QFileDialog dialog(0);
  dialog.setFileMode(QFileDialog::ExistingFile);
  dialog.setFilter(QDir::Files);  //<--------------------------All files except executable files.???
  dialog.exec();
  return 0;
}

To copy to clipboard, switch view to plain text mode

dialog.setFilter(QDir::Files); //<--------------------------All files except executable files.???

Very interesting problem. There is a QDir::Readable, a QDir::Writable, and a QDir::Executable. All three must be combined with QDir::Files. If QDir::Files shows all files, why add one of the three? To show all files + readable, writable, and executable files? Would only make sense if QDir::Files alone shows nothing. Or QDir::Files shows all, but the writable, readable, executable flags actually subtract files with those permissions. Looks like a minor documentation bug to me.
Try: dialog.setFilter(QDir::Files|QDir::Readable|QDir:: Writable);
or: dialog.setFilter(QDir::Files|QDir::executable);
Just as an experiment. What is the result?

I tried
dialog.setFilter (QDir:: Files | QDir:: Readable | QDir:: Writable);
and so I see all the files except "exe" but I do not see the folders.
Same problem for these two cases:
dialog.setFilter (QDir:: Dirs | QDir:: Files | QDir:: Readable | QDir:: Writable) and
dialog.setFilter (QDir:: Dirs | QDir:: Files | QDir:: Readable | QDir:: Writable | QDir:: Modified);

Instead
dialog.setFilter (QDir:: Files | QDir:: Executable);
I only see the files. "exe" without all the other folders and files.

So,

dialog.setFilter (QDir:: Files | QDir:: Readable | QDir:: Writable);

goes into the right direction.

I don't know the solution, but I would now try:
dialog.setFilter (QDir::AllDirs| QDir:: Readable | QDir:: Writable)

thanks for your help, but unfortunately it does not work that way. :-(

Looks like a Qt bug to me. According to the assistant:
QDir::AllDirs 0x400 List all directories; i.e. don't apply the filters to directory names.
But the executables are filtered. And of course, folders are executable, else it would be impossible to enter them.
At least under Linux.
