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
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
