如何使PySide窗口在所有其他窗口之上弹出
如何使PySide窗口在所有其他窗口之上弹出
提问于 2017-03-05 22:03:49
下面是一个PyQt示例，说明如何使用“WindowStaysOnTopHint”，使对话框弹出，显示在所有其他窗口之上：
#copied from: http://stackoverflow.com/questions/1925015/pyqt-always-on-top
import sys
from PyQt4 import QtGui, QtCore
class mymainwindow(QtGui.QMainWindow):
def __init__(self):
QtGui.QMainWindow.__init__(self, None, QtCore.Qt.WindowStaysOnTopHint)
app = QtGui.QApplication(sys.argv)
mywindow = mymainwindow()
mywindow.show()
app.exec_()“WindowStaysOnTopHint”属性似乎是使窗口在所有其他窗口之上弹出的关键。但是，我不知道如何使用'WindowStaysOnTopHint‘属性来使“文件夹实用程序”窗口(在下面的脚本中)弹出，从而显示出自己在所有其他窗口之上。我尝试在self.initUI()附近插入几个选项，如下所示，但是没有什么使“文件夹实用程序”窗口(在下面的脚本中)弹出高于所有其他窗口。
下面是剧本：
import os
import sys
# Based on 'http://stackoverflow.com/questions/22363123/pyside-get-directory-selected', but with many changes I made
from PySide import QtCore
from PySide import QtGui
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
#self.setWindowFlags(self.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)
#flags = QtCore.Qt.WindowFlags()# The line above prevented the
# window from appearing at all
#flags |= QtCore.Qt.WindowStaysOnTopHint # This line and the line
# above had no effect.
self.initUI()
self.setWindowFlags(self.windowFlags() | QtCore.Qt.WindowStaysOnTopHint)
def initUI(self):
QtGui.QToolTip.setFont(QtGui.QFont('SansSerif', 10))
self.setToolTip('This is a <b>QWidget</b> widget')
# EditText Field
labelNuDirName = QtGui.QLabel('New Folder Name:', self)
labelNuDirName.move(15, 10)
self.etNuDirName = QtGui.QLineEdit('', self)
self.etNuDirName.resize(self.etNuDirName.sizeHint())
self.etNuDirName.move(110, 7)
# Folder Browser
lbBroswer = QtGui.QLabel('Directory:', self)
lbBroswer.move(15, 40)
self.etBrowser = QtGui.QLineEdit('', self)
self.etBrowser.resize(210,20)#width, height https://srinikom.github.io/pyside-docs/PySide/QtGui/QWidget.html#PySide.QtGui.PySide.QtGui.QWidget.resize
self.etBrowser.move(90, 37)
self.etBrowser.setEnabled(0)
# self.etBrowser.isReadOnly = 0
btnBrowse = QtGui.QPushButton('...', self)
btnBrowse.setToolTip('Select directory ...')
btnBrowse.resize(30,20)
btnBrowse.move(305, 37)
btnBrowse.clicked.connect(self.selectDirectory)
# Button UI
btn = QtGui.QPushButton('Create Folder', self)
btn.setToolTip('This creates the folders.')
btn.resize(btn.sizeHint())
btn.move(5, 60)
btn.clicked.connect(self.generateFolders)
###Folder Selected Show
# label_NuDirSelected = QtGui.QLabel('', self)
# self.etNuDirName.resize(210,20)#width, height https://srinikom.github.io/pyside-docs/PySide/QtGui/QWidget.html#PySide.QtGui.PySide.QtGui.QWidget.resize
# lbBroswer.move(5, 80)
self.resize(350, 150)
self.center()
self.setWindowTitle('Folder Utility')
self.show()
def center(self):
qr = self.frameGeometry()
cp = QtGui.QDesktopWidget().availableGeometry().center()
qr.moveCenter(cp)
self.move(qr.topLeft())
def selectDirectory(self):
dialog = QtGui.QFileDialog
selected_directory = dialog.getExistingDirectory(None,
title,
startingDir,
QtGui.QFileDialog.ShowDirsOnly)
# Use the selected directory...
self.etBrowser.setText(selected_directory)
print 'selected_directory:', selected_directory
# txt4__label_NuDirSelected = 'Directory you selected = "' + selected_directory + '"'
# self.label_NuDirSelected.setText(txt4__label_NuDirSelected)
def generateFolders(self):
existing_directory = self.etBrowser.text()
NuDirName = self.etNuDirName.text()
filePath = str(existing_directory) + os.sep + str(NuDirName)
if not os.path.exists(filePath):
os.makedirs(filePath)
if os.path.exists(filePath):
print 'Successfully Created Folders!'
def main():

我使用以下代码使PyQt4窗口成为最顶部的窗口，并在Windows 10 64位环境中将其置于最前面(所有其他窗口前面)：
self.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)
# The following is drawn from: https://stackoverflow.com/questions/12118939/how-to-make-a-pyqt4-window-jump-to-the-front
# the following will remove minimized status
# and restore window with keeping maximized/normal state
self.setWindowState(self.windowState() & ~QtCore.Qt.WindowMinimized | QtCore.Qt.WindowActive)
# this will activate the window
self.activateWindow()Stack Overflow用户

我想我现在知道问题在哪里了。每当您重置窗口标志时，Qt也会在内部调用setParent() --后者将隐藏该窗口。因此，在调用show()之后，必须始终显式地调用setWindowFlags()。
将self.initUI() (称为show())放在Example.__init__()中的最后一个。或从self.show()中删除initIU，并在main()中添加行ex.show()。
