MFC:如何根据单击按钮交替显示两个组框? [英] MFC : How to display two group boxes alternatively based on a button click?

问题描述

我有两个分组框，每个分组框包含 2 个单选按钮，每个参考图.我需要一种机制，其中 button1 的 init 阶段值显示文本Group box 2"，并且对话框中显示的当前分组框是分组框 1.当我单击单选按钮 1 = Group Box 2 时，当前会发生以下情况:

I have two group boxes containing 2 radio button each refer figure. I need a mechanism wherein the init stage value of button1 shows text "Group box 2" and the current group box displayed on the dialog is group box 1. As I click on the radio button1 = Group Box 2 currently the following happens:

1. 按钮 1 中的文本更改为分组框 1

1. The text in button 1 changes to group box 1

组框2显示在对话框中

隐藏分组框 1

我知道如何隐藏分组框我不确定是切换部分

I know how to hide the group boxes what I am not sure is the toggling part

推荐答案

您可以使用以下方法:创建一个函数来显示/隐藏相关组框并更新按钮上的文本.

You can use the following approach: Create a function that will show/hide the relevant group box and update the text on the button.

1. 您可以使用此功能来显示/隐藏控件和组.接收到的参数是电台ID和分组框.

1. You can use this function to show/hide the controls and the group. The parameter received are the IDs of the radios and the group box.

void CMFCApplication2Dlg::ShowHideControls(BOOL hide, int groupID, int radio1ID, int radio2ID)
{
    GetDlgItem(groupID)->ShowWindow(hide ? SW_HIDE : SW_NORMAL);
    GetDlgItem(radio1ID)->ShowWindow(hide ? SW_HIDE : SW_NORMAL);
    GetDlgItem(radio2ID)->ShowWindow(hide ? SW_HIDE : SW_NORMAL);
}

创建一个控制切换的函数:

Create a function that control the toggling:

void CMFCApplication2Dlg::ToggleGroup(BOOL group1Visible)
{
    ShowHideControls(group1Visible, IDC_MY_GROUP, IDC_RADIO1, IDC_RADIO2);
    ShowHideControls(!group1Visible, IDC_MY_GROUP2, IDC_RADIO3, IDC_RADIO4);

    CString txt;
    txt.Format(L"Group Box %d", group1Visible ? 1 : 2);
    GetDlgItem(IDC_BUTTON_TOGGLE)->SetWindowText(txt);
}

从以下位置调用 ToggleGroup:

a) OnInitDialog 带有 FALSE 参数.

a) OnInitDialog with FALSE parameter.

b) 在按钮单击事件处理程序中.

b) In button click event handler.
