The documentation for QFileDialog.getOpenFileName does not provide any clue on how to filter only executables using a const QString &filter = QString()
. Here's the code for my action using PyQt5:
from PyQt5.QtWidgets import QAction, QFileDialog
from PyQt5.QtCore import QDir
from os import path
class OpenSourcePortAction(QAction):
def __init__(self, widget, setSourcePort, config, saveSourcePortPath):
super().__init__('&Open Source Port', widget)
self.widget = widget
self.setShortcut('Ctrl+O')
self.setStatusTip('Select a source port')
self.triggered.connect(self._open)
self.setSourcePort = setSourcePort
self.config = config
self.saveSourcePortPath = saveSourcePortPath
def _open(self):
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
fileName, _ = QFileDialog.getOpenFileName(
self.widget, "Select a source port", self.config.get("sourcePortDir"), "Source Ports (gzdoom zandronum)", options=options)
if fileName:
self.saveSourcePortPath(fileName)
self.setSourcePort(fileName)
On linux, naturally, I have no file extensions for executables, but I need to filter.exe extensions on windows (Which I intend to provide a version for). Also, there's no overloaded method that allows QDir::Executable . How can I use QFileDialog.getOpenFileName
while filtering only executables, no matter which platform it's running on?
If you want a more personalized filter then you have to use a proxyModel but for this you cannot use the getOpenFileName method since the QFileDialog instance is not easily accessible since it is a static method.
class ExecutableFilterModel(QSortFilterProxyModel):
def filterAcceptsRow(self, source_row, source_index):
if isinstance(self.sourceModel(), QFileSystemModel):
index = self.sourceModel().index(source_row, 0, source_index)
fi = self.sourceModel().fileInfo(index)
return fi.isDir() or fi.isExecutable()
return super().filterAcceptsRow(source_row, source_index)
class OpenSourcePortAction(QAction):
def __init__(self, widget, setSourcePort, config, saveSourcePortPath):
super().__init__("&Open Source Port", widget)
self.widget = widget
self.setShortcut("Ctrl+O")
self.setStatusTip("Select a source port")
self.triggered.connect(self._open)
self.setSourcePort = setSourcePort
self.config = config
self.saveSourcePortPath = saveSourcePortPath
def _open(self):
proxy_model = ExecutableFilterModel()
options = QFileDialog.Options()
options |= QFileDialog.DontUseNativeDialog
dialog = QFileDialog(
self.widget, "Select a source port", self.config.get("sourcePortDir")
)
dialog.setOptions(options)
dialog.setProxyModel(proxy_model)
if dialog.exec_() == QDialog.Accepted:
filename = dialog.selectedUrls()[0].toLocalFile()
self.saveSourcePortPath(fileName)
self.setSourcePort(fileName)
