QPushButton图标未出现

Question

I created a button like this:

icontest = QtGui.QIcon('test.gif');
self.TestButton = QtGui.QPushButton("Test")
self.TestButton.setEnabled(False)
self.TestButton.setIcon(icontest)
self.TestButton.setIconSize(QtCore.QSize(25, 25))
self.TestButton.clicked.connect(goToTestHandler)
self.layout.addWidget(self.TestButton, 0, 1)
... some loading ...
self.TestButton.setEnabled(True)

the button appears, but without the icon - no exception thrown

Answer 1

I can reproduce that behavior only when the path passed to the QIcon constructor is wrong. Otherwise the icon is displayed.

Answer 2

I have created a button with image in a table cell and the image is appering and working . here is the code.

    newitem = QPushButton(self)
    newitem.setFlat(True)
    newitem.setAutoFillBackground(True)

    palette = newitem.palette();
    palette.setColor(QPalette.Button,QColor(255,255,255));
    newitem.setPalette(palette);
    newitem.setIcon(QIcon("__32__Setting-icon.png"));
    newitem.setIconSize(QSize(22,22));
    self.job_table.setCellWidget(self.table_job_rowCount,6,newitem )
