示例1: copy_clipboard
# 需要导入模块: from PySide.QtGui import QImage [as 别名]
# 或者: from PySide.QtGui.QImage import fromData [as 别名]
def copy_clipboard(self):
from io import BytesIO
buf = BytesIO()
self.fig.savefig(buf)
QApplication.clipboard().setImage(QImage.fromData(buf.getvalue()))
buf.close()示例2: clipboard_handler
# 需要导入模块: from PySide.QtGui import QImage [as 别名]
# 或者: from PySide.QtGui.QImage import fromData [as 别名]
def clipboard_handler(event):
if event.key == 'ctrl+c':
# store the image in a buffer using savefig(), this has the
# advantage of applying all the default savefig parameters
# such as background color; those would be ignored if you simply
# grab the canvas using Qt
buf = io.BytesIO()
fig.savefig(buf)
QApplication.clipboard().setImage(QImage.fromData(buf.getvalue()))
buf.close()示例3: _setWallpaper
# 需要导入模块: from PySide.QtGui import QImage [as 别名]
