Set waitcursor on qtextedit

Blackbear

By default in a Qt GUI app the cursor changes to an IBeam when the mouse moves over a textedit. How can I change it to a waitcursor? I can set the waitcursor to the whole app but that is not what I need. I want to keep the arrow cursor except when the mouse cursor moves over textedit.

This is what I have tried with no luck.

@ def run_process(self):
self.textEdit.setCursor(Qt.WaitCursor)
self.textEdit.clear()
self.textEdit.append("Standby, this proc takes time.")
QApplication.processEvents()
process = subprocess.Popen(['ext_proc.sh'], stdout=subprocess.PIPE)
results = process.communicate()[0]
self.textEdit.clear()
self.textEdit.append(results)
self.textEdit.setCursor(Qt.IBeamCursor)@

The cursor is being set by the QTextEdit's viewport, not the QTextEdit itself. Try the following:

@
from PyQt4.QtCore import *
from PyQt4.QtGui import *

if name=="main":
from sys import argv, exit

class Widget(QWidget):
    def __init__(self, parent=None, **kwargs):
        QWidget.__init__(self, parent, **kwargs)

        l=QVBoxLayout(self)

        t=QTextEdit()
        t.viewport().setCursor(Qt.WaitCursor)
        l.addWidget(t)

a=QApplication(argv)
w=Widget()
w.show()
w.raise_()
exit(a.exec_())

Hope this helps ;o)

I used the following and it changed to cursor over the textwidget to an arrow until the process finished and then set it back to an Ibeam.

@ def run_process(self):
self.textEdit.viewport().setCursor(Qt.WaitCursor)
self.textEdit.clear()
self.textEdit.append("Standby, this proc takes time.")
QApplication.processEvents()
process = subprocess.Popen(['ext_proc.sh'], stdout=subprocess.PIPE)
results = process.communicate()[0]
self.textEdit.clear()
self.textEdit.append(results)
self.textEdit.viewport().setCursor(Qt.IBeamCursor)@

The cursor changes to an arrow even if I comment out my setCursor commands. That tells me that the cursor setting is getting over ridden.

As a test I set WaitCursor on textEdit in the init function and sure enough it shows up. As soon as I start the subprocess it turns into an arrow until the subprocess is done.

My cursor setting is getting over ridden but I'm not sure why or how.

Switch to QProcess, which is what I intended to use from the start, and had some success.

I can now set the wait cursor for the textWidget only.

@def run_process(self):
self.textEdit.viewport().setCursor(Qt.WaitCursor)
self.textEdit.clear()
self.textEdit.append("Standby, this proc takes time.")
self.runner = QProcess(self)
self.runner.readyReadStandardOutput.connect(self.GetStd)
self.runner.start('ext_proc.sh')

def GetStd(self)
StdOut = str(self.runner.readAllStandardOutput())
self.textEdit.append(StdOut)
self.textEdit.viewport().setCursor(Qt.IBeamCursor@

The problem now is that the Ibeam cursor is reset upon the first input of standard out. However, ext_proc.sh is still running.

Tried some things with waitForFinished() but it froze the interface.

Is there a way to keep the wait cursor until the external process is complete without locking the GUI?

Thanks in advance,
Cheers,
