我目前的代码适用于更新MainWindow中2个textBrowsers中的x-y坐标,但当光标位于textBrowsers内部时,它不起作用。
对于这个例子,我希望当光标移动到textBrowser_1内部时,坐标才会更新。
from PyQt4 import QtCore
from PyQt4 import QtGui
from PyQt4.QtGui import QApplication, QMainWindow
import sys
class Ui_MainWindow(object):
def setupUi(self, MainWindow):
MainWindow.resize(800, 132)
self.centralwidget = QtGui.QWidget(MainWindow)
self.horizontalLayout = QtGui.QHBoxLayout(self.centralwidget)
self.textBrowser_1 = QtGui.QTextBrowser(self.centralwidget)
self.horizontalLayout.addWidget(self.textBrowser_1)
self.textBrowser_2 = QtGui.QTextBrowser(self.centralwidget)
self.horizontalLayout.addWidget(self.textBrowser_2)
MainWindow.setCentralWidget(self.centralwidget)
self.menubar = QtGui.QMenuBar(MainWindow)
self.menubar.setGeometry(QtCore.QRect(0, 0, 800, 22))
MainWindow.setMenuBar(self.menubar)
self.statusbar = QtGui.QStatusBar(MainWindow)
MainWindow.setStatusBar(self.statusbar)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
class MyMainScreen(QMainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.ui = Ui_MainWindow() # This is from a python export from QtDesigner
self.ui.setupUi(self)
self.setMouseTracking(True)
self.ui.textBrowser_1.installEventFilter(self)
# self.ui.textBrowser_1.setMouseTracking(True)
# self.ui.menubar.setMouseTracking(True)
# self.ui.statusbar.setMouseTracking(True)
def setMouseTracking(self, flag):
def recursive_set(parent):
for child in parent.findChildren(QtCore.QObject):
try:
child.setMouseTracking(flag)
except:
pass
recursive_set(child)
QtGui.QWidget.setMouseTracking(self, flag)
recursive_set(self)
def mouseMoveEvent(self, event):
self.ui.textBrowser_1.setText(str(event.x()))
self.ui.textBrowser_2.setText(str(event.y()))
QtGui.QMainWindow.mouseMoveEvent(self, event)
if __name__ == "__main__":
app = QApplication(sys.argv)
mainscreen = MyMainScreen()
mainscreen.show()
app.exec_()
这是程序的样子: mouseTest
答案 0 :(得分:0)
从您的代码示例中,您可能已经尝试过事件过滤器,但这可能是最佳解决方案。诀窍是将其安装在小部件的viewport上(如果有的话):
class MyMainScreen(QMainWindow):
def __init__(self, parent=None):
QtGui.QMainWindow.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.ui.textBrowser_1.setMouseTracking(True)
self.ui.textBrowser_1.viewport().installEventFilter(self)
def eventFilter(self, source, event):
if event.type() == QtCore.QEvent.MouseMove:
self.ui.textBrowser_1.setText(str(event.x()))
self.ui.textBrowser_2.setText(str(event.y()))
return QtGui.QMainWindow.eventFilter(self, source, event)
