Question

我需要从行号Y

开始从textctrl中间删除X行

有没有简单的方法可以做到这一点？我看不到一个：似乎我必须以某种方式搜索TextCtrl的内容，计算换行符以找到Y的位置......

    if self._log.GetNumberOfLines() > MAX_LINES:
        if self._log.GetLineText(DELETION_POINT) != DELETION_LINE:
            start = self._log.XYToPosition(0, DELETION_POINT)
            self._log.SetInsertionPoint(start)
            self._log.WriteText(DELETION_LINE)
        while (self._log.GetNumberOfLines() > MAX_LINES):
            start = self._log.XYToPosition(0, DELETION_POINT+1)
            len = self._log.GetLineLength(DELETION_POINT+1)
            self._log.Remove(start, start+len+1)
