如何在主 window 中更改 PyQt5 目录视图的大小?
How to change the size of PyQt5 directory view in the main window?
我正在做一个 PyQt5 项目,它需要 PyQt5 的文件夹查看器 QTreeView
。为了放更多的东西,我尝试改变树视图的大小但没有成功。这是来自 Pythonspot 的代码:
import sys
from PyQt5.QtWidgets import QApplication, QFileSystemModel, QTreeView, QWidget, QVBoxLayout
from PyQt5.QtGui import QIcon
class App(QWidget):
def __init__(self):
super().__init__()
self.title = 'PyQt5 file system view - pythonspot.com'
self.left = 10
self.top = 10
self.width = 640
self.height = 480
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
self.model = QFileSystemModel()
self.model.setRootPath('')
self.tree = QTreeView()
self.tree.setModel(self.model)
self.tree.setAnimated(False)
self.tree.setIndentation(20)
self.tree.setSortingEnabled(True)
self.tree.setWindowTitle("Dir View")
self.tree.resize(640, 200)
windowLayout = QVBoxLayout()
windowLayout.addWidget(self.tree)
self.setLayout(windowLayout)
self.show()
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = App()
sys.exit(app.exec_())
我通过
更改树视图
self.tree.resize(640, 200)
为什么它不起作用?
布局用于确定您正在使用的小部件的位置和大小,因此在您的情况下,即使您使用调整大小,大小也不会改变,相反,您应该设置一个固定大小,这样布局就不会更改 QTreeView
.
