Tips

スクロールバーを先頭に移動

TextEdit

textEdit.verticalScrollBar().triggerAction(QtGui.QAbstractSlider.SliderToMinimum)

チェックボックスをチェック

http://pyqt.sourceforge.net/Docs/PyQt4/qt.html#CheckState-enum

from PyQt4 import QtCore as qt
 
chkCountWs = gui.QCheckBox(u"空白計測")
chkCountWs.setCheckState(qt.Qt.Checked)

ファイル選択

dialog = QtGui.QFileDialog()
dialog.setFileMode(gui.QFileDialog.AnyFile)
dialog.setFilter('images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)')
if dialog.exec_():
    fileNames = dialog.selectedFiles()    
    for f in fileNames:
        print f
