Public 成员函数

 DACommandWithRedoCount (QUndoCommand *par=nullptr)
 
virtual void redo () override
 
virtual bool exec ()
 执行函数，此函数返回false，说明执行失败，不应该被放入command stack中，在DACommandWithRedoCount中，exec函数应该替代redo函数
 

Protected 属性

详细描述

加上计数的cmd TODO:这个类的名字需要修改为DACommandInitialSkipRedo

auto cmd = new DACommandDataFrame_iat(...);
cmd->redo();
void DACommandDataFrame_iat::redo()
{
addRedoCnt();
if (isEqualTwo()) {
//第二次执行跳过，推入栈
return;
}
。。。
}
DA::DACommandDataFrame_iat
添加变量命令
Definition DACommandsDataFrame.h:57

或者

auto cmd = new DACommandDataFrame_other(...);
cmd->isvalid();
void DACommandDataFrame_other::redo()
{
addRedoCnt();
run();
}

成员函数说明

◆ exec()

bool DA::DACommandWithRedoCount::exec ( )
virtual

执行函数，此函数返回false，说明执行失败，不应该被放入command stack中，在DACommandWithRedoCount中，exec函数应该替代redo函数
