Question

我制作了一个应用程序来练习c ++和qt（初级水平）

看起来像这样： （麻将主题！）

Atm，它所做的就是： http://imgur.com/cnXfWZh

非常简单，但我想添加一些功能。

问题是，我不认为添加它们会那么困难（至少对我而言）。

＆＃34;玩家1＆＃34;复选框

只需勾选＆＃34;播放器1＆＃34;复选框应该允许在gif中看到的操作。（现在总是允许的;不需要勾选方框）
勾选该框时，还应将每个图块图标添加到＆＃34; graphicsView＆＃34;区域，在单击每个图块时，按照输出内部的相同顺序＆＃34; textEdit框1＆＃34;。

（＆＃34; textEdit框1＆＃34;的字符串附加功能之上，现在已经可以使用了）
＆＃34; textEdit＆＃34;最多允许13个图块。框和＆＃34; graphicsView＆＃34;区域

像这样：http://imgur.com/SUWHJSK

我正在拯救＆＃34; Wall＆＃34;复选框应该在以后执行：）

我的代码可能是灾难性的，抱歉。＆lt; - 仍然非常初学者但是这里：

我真的很喜欢和欣赏一些帮助，即使它不是我所描述的所有内容。

我没有看到您的复选框的任何信号/插槽连接，因此它只是默认状态，即已选中和未选中状态。如果要将复选框链接到textedit，请考虑

connect(ui->player1_checkbox, SIGNAL(stateChanged(int)), this, SLOT(toggleTextEdit()));

toggleTextEdit（）可能是

void MainWindow::toggleTextEdit()
        {
         if(ui->player1_checkbox->isChecked())
             ui->textEdit->setEnabled(true);
         else
             ui->textEdit->setEnabled(false);
        }

对于图形视图，您可能必须创建一个大小为13的数组，并在您更改鼠标焦点下的按钮时更新数组，数组内容以类似于

的方式更新

array[counter%13] = currentButtonNumber;
counter = counter+1;

然后，您可以使用与数组元素对应的图标更新图形视图。变量counter用于跟踪单击的按钮并相应地更新数组，每次第13次点击从0开始。希望这有效。

复选框切换QPushbutton函数（追加字符串+显示自定义图标）
