Native QFileDialog in OSX with multi filters not updated

[mpergand]

Hi all,

The file list is not updated when a filter is selected via the popup menu, so the selectable items stay grayed, and the very weird thing is that dispite there are grayed there are selectable !
Very disturbing user experience ...

You can see this behavior in QtCreator itself with " Open File With" in the File menu.
Any workaround to force the items list to redraw ?

I'm on OSX 10.9, Qt 5.6

Hi,

Can you provide a minimal compilable example that reproduces that behavior ?

Hi,

Very simple:

#include <QApplication>
#include <QFileDialog>
#include <QString>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    const QString filters = "*.png;;*.jpg";
    QString filepath=QFileDialog::getOpenFileName(0, 0, 0, filters);

    return 0;
}

I'm using OSX 10.9 Mavericks, Qt 5.6.1 and 5.7.1
This bug exists in all Qt apps, for example VirtualBox.
In QtCreator main menu, select File->Open File With
and change the type of file with the popup menu button, the file list is not updated.
This bug doesn't occur on Ubuntu.

I tried this on my system and it worked. Qt 5.6.0 OSX 10.10.5. I did have Mavericks on my laptop a few years ago and don't notice any problem. I don't have 5.6.1 or 5.7.1 so I can't test this.

I noticed a difference between your filters and ones I use (placement of the semi-colons). This is an example of a filter that I just tested with. When I change the selection of the filter it does update the file list (black for items that match the filter, grey for items that don't match the selected filter):

QString LCompFiles::LoadFileFilters(void) const
{
	QString				file_filters;
	
	file_filters = QStringLiteral("All Compensation Maps (*.bin *.res *.dat *.cmp *.asc *.enc *.prg *.cfg *.smp *.asc Y* *.map "\
						"*.vo2 *.txt *.gec *.gecs *.3pg *.xdx *.ydy *.zdz *.ecd *.v3d *.nob)");
	file_filters += QStringLiteral(";;Apogee Maps (*.res)");
	file_filters += QStringLiteral(";;Automation Software Maps (*.dat)");
	file_filters += QStringLiteral(";;Brown and Sharpe Maps (*.cmp *.asc *.dat *.enc)");
	file_filters += QStringLiteral(";;Capps Maps (*.bin *.dat)");
	file_filters += QStringLiteral(";;Chorus Maps (*.dat)");
	file_filters += QStringLiteral(";;CMM Manager Maps (*.map *.txt)");
	file_filters += QStringLiteral(";;DEA Maps (*.dat)");
	file_filters += QStringLiteral(";;DEVA Maps (*.xdx *.ydy *.zdz *.txt *.nob)");
	file_filters += QStringLiteral(";;Leitz Maps (*.txt)");
	file_filters += QStringLiteral(";;LK Maps (*.prg)");
	file_filters += QStringLiteral(";;Metrolog Maps (*.res)");
	file_filters += QStringLiteral(";;OpenDMIS Maps (*.ecd)");
	file_filters += QStringLiteral(";;Renishaw Compensation Maps (*.gec *.gecs *.3pg)");
	file_filters += QStringLiteral(";;Sheffield Maps (*.cfg *.smp)");
	file_filters += QStringLiteral(";;Verisurf Compensation Maps (*.v3d)");
	file_filters += QStringLiteral(";;Virtual DMIS Maps (*.txt)");
	file_filters += QStringLiteral(";;Wenzel Maps (*.vo2)");
	file_filters += QStringLiteral(";;Zeiss Maps (*.dat Y*)");

	return file_filters;
}

I also tried the filters with VirtualBox. It all looks good.

After further investigations, it turns out it's a bug of Mavericks itself !
NSOpenPanel bug
My bad, sorry.
