示例1: _getCursorSelectAll
# 需要导入模块: from PyQt5.QtGui import QTextCursor [as 别名]
# 或者: from PyQt5.QtGui.QTextCursor import hasSelection [as 别名]
def _getCursorSelectAll(self, morph):
'''
Cursor on entire document (text) of a morph (DocumentElement) of type Text.
morph may be empty of text.
!!! Cursor may not hasSelection() if morph is empty of text.
'''
cursor = QTextCursor(morph.document())
cursor.setPosition(0)
cursor.clearSelection()
# programmatic selection requires movePosition(), not setPosition()
cursor.movePosition(QTextCursor.End, QTextCursor.KeepAnchor)
# In Qt, cursor is valid for further operations regardless of whether hasSelection()
# ensure document not empty => cursor.hasSelection
assert morph.document().isEmpty() or cursor.hasSelection()
return cursor示例2: get_find_range
# 需要导入模块: from PyQt5.QtGui import QTextCursor [as 别名]
# 或者: from PyQt5.QtGui.QTextCursor import hasSelection [as 别名]
def get_find_range(self):
tc = QTextCursor(self.range_sel.cursor) # copy of range cursor
if not tc.hasSelection() :
tc.select(QTextCursor.Document)
return tc
