项目
03/01/2013

添加一个单选按钮 CTaskDialog。

void CTaskDialog::AddRadioButton(
   int nRadioButtonID,
   const CString& strCaption,
   BOOL bEnabled = TRUE
);

参数

[in] nRadioButtonID
单选按钮的ID号。
[in] strCaption
CTaskDialog 单选按钮旁显示的字符串。
[in] bEnabled
指示的boolean参数单选按钮是否启用。

备注

CTaskDialog类选件的单选按钮可以收集来自用户的信息。使用函数 CTaskDialog::GetSelectedRadioButtonID 确定哪个单选按钮被选定。

CTaskDialog 不需要 nRadioButtonID 参数为每个单选按钮是唯一的。但是，因此，如果您无需为每个单选按钮，使用一个不同的标识符可能产生意外行为。

示例

// TODO: Replace the strings below with the appropriate message, 
// main instruction, and dialog title
CString message("This is an important message to the user.");
CString mainInstruction("Important!\nPlease read!");
CString title("Alert Dialog");

CTaskDialog taskDialog(message, mainInstruction, title, 
    TDCBF_YES_BUTTON | TDCBF_NO_BUTTON | TDCBF_CANCEL_BUTTON );

taskDialog.AddRadioButton(201, L"First option");
taskDialog.AddRadioButton(202, L"Second option");
taskDialog.AddRadioButton(203, L"Third option");

taskDialog.DoModal();
int selection = taskDialog.GetSelectedRadioButtonID();

switch(selection)
{
case 201:
    // TODO: Place processing here for the first 
    // radio button.
    break;

case 202:
    // TODO: Place processing here for the second 
    // radio button.
    break;

case 203:
    // TODO: Place processing here for the third 
    // radio button.
    break;

default:
    break;
}

// Remove all the radio buttons so that we can use the same task
// dialog with new radio buttons.
taskDialog.RemoveAllRadioButtons();

taskDialog.AddRadioButton(301, L"New first option");
taskDialog.AddRadioButton(302, L"New second option");
taskDialog.AddRadioButton(303, 
    L"New third option should be disabled");

// Change the default radio button to the second option
taskDialog.SetDefaultRadioButton(302);

// Make sure the third option is disabled.
if (taskDialog.IsRadioButtonEnabled(303))
{
    taskDialog.SetRadioButtonOptions(303, FALSE);
}

taskDialog.DoModal();
selection = taskDialog.GetSelectedRadioButtonID();

switch(taskDialog.GetSelectedRadioButtonID())
{
case 301:
    // TODO: Place processing here for new first 
    // command button control.
    break;

case 302:

    // command button control.
    break;

case 303:
    // TODO: Place processing here for the new third 
    // command button control.
    break;

default:
    break;
}

// Remove all the radio button controls and add new ones from
// the string table resource.
taskDialog.RemoveAllRadioButtons();
taskDialog.LoadRadioButtons(1001, 1005);
