示例1: _cursor_moved
# 需要导入模块: from PyQt5.QtGui import QTextCursor [as 别名]
# 或者: from PyQt5.QtGui.QTextCursor import positionInBlock [as 别名]
def _cursor_moved(self):
tc = QTextCursor(self.Editor.textCursor()) # copy of cursor
self.ColNumber.setText( str( tc.positionInBlock() ) )
tb = tc.block()
if tb == self.last_text_block :
return # still on same line, nothing more to do
# Fill in line-number widget, line #s are origin-1
self.LineNumber.setText( str( tb.blockNumber()+1 ) )
# Fill in the image name and folio widgets
pn = self.page_model.page_index(tc.position())
if pn is not None : # the page model has info on this position
self.ImageFilename.setText(self.page_model.filename(pn))
self.Folio.setText(self.page_model.folio_string(pn))
else: # no image data, or cursor is above page 1
self.ImageFilename.setText('')
self.Folio.setText('')
# Change the current-line "extra selection" to the new current line.
# Note: the cursor member of the extra selection may not have a
# selection. If it does, the current line highlight disappears. The
# cursor "tc" may or may not have a selection; to make sure, we clone
# it and remove any selection from it.
cltc = QTextCursor(tc)
cltc.setPosition(tc.position(),QTextCursor.MoveAnchor)
# Set the cloned cursor into the current line extra selection object.
self.current_line_sel.cursor = cltc
# Re-assign the list of extra selections to force update of display.
self.Editor.setExtraSelections(self.extra_sel_list)示例2: _cursor_moved

# to have no selection. Yes, we are here because the cursor moved,

# of a shift-click extending the selection.
