[英]how to create folder view in pyqt inside main window
我正在嘗試實現文件夾查看器來查看特定路徑的結構。 這個文件夾視圖應該看起來像PyQT中的樹小部件,我知道文件對話框可以幫助,但我需要在我的主窗口中。
我試圖使用QTreeWidget實現這一點,我使用一個遞歸函數循環文件夾,但這太慢了。 因為它需要遞歸大量的文件夾。 這是正確的方法嗎? 或者有一個現成的qt解決方案來解決這個問題。
檢查下圖。
對於PyQt5我做了這個功能:
def load_project_structure(startpath, tree):
"""
Load Project structure tree
:param startpath:
:param tree:
:return:
"""
import os
from PyQt5.QtWidgets import QTreeWidgetItem
from PyQt5.QtGui import QIcon
for element in os.listdir(startpath):
path_info = startpath + "/" + element
parent_itm = QTreeWidgetItem(tree, [os.path.basename(element)])
if os.path.isdir(path_info):
load_project_structure(path_info, parent_itm)
parent_itm.setIcon(0, QIcon('assets/folder.ico'))
else:
parent_itm.setIcon(0, QIcon('assets/file.ico'))
然后我稱之為:
load_project_structure("/your/path/here",projectTreeWidget)
使用模型和視圖。
"""An example of how to use models and views in PyQt4.
Model/view documentation can be found at
http://doc.qt.nokia.com/latest/model-view-programming.html.
"""
import sys
from PyQt4.QtGui import (QApplication, QColumnView, QFileSystemModel,
QSplitter, QTreeView)
from PyQt4.QtCore import QDir, Qt
if __name__ == '__main__':
app = QApplication(sys.argv)
# Splitter to show 2 views in same widget easily.
splitter = QSplitter()
# The model.
model = QFileSystemModel()
# You can setRootPath to any path.
model.setRootPath(QDir.rootPath())
# List of views.
views = []
for ViewType in (QColumnView, QTreeView):
# Create the view in the splitter.
view = ViewType(splitter)
# Set the model of the view.
view.setModel(model)
# Set the root index of the view as the user's home directory.
view.setRootIndex(model.index(QDir.homePath()))
# Show the splitter.
splitter.show()
# Maximize the splitter.
splitter.setWindowState(Qt.WindowMaximized)
# Start the main loop.
sys.exit(app.exec_())
