MFC PropertyGrid 控件在visual studio 的对话框编辑器中是如何工作的？

Question

In the visual studio dialog editor i can add a MFC Property Grid control to the dailog. How can i customize its content, and set options like allowing the user to edit the contents of it when the program using it is running, or how i can change the contents of it using c++? When i add something like a button or and edit control it displays on the dailog box when the program is running, while when i add a MFC Property Grid the dailog isnt even being displayed.

Here is a picture of the visual studio dialog editor and a MFC property control grid in the middle of the dailog with contents i dont know how to change.

Answer 1

Simple tutorial of CMFCPropertyGridCtrl：

1.Create a dialog-based MFC project, drag a CMFCPropertyGridCtrl into it, and adjust the size. Then change the ID for the control to IDC_MFCPROPERTYGRID_TEST, and use Add Varible to add a variable m_propertyGrid to the control. Change the setting of Notify to True .

Description Rows Count refers to the number of rows in the description section below.

Enable Description Area indicates whether to enable the following description function.

Enable Header indicates whether to start the header.

Mark Modified Properties indicates whether to highlight the changes.

2.Set interface Add the following code in OnInitDialog()

HDITEM item; 
item.cxy=120; 
item.mask=HDI_WIDTH; 
m_propertyGrid.GetHeaderCtrl().SetItem(0, new HDITEM(item)); 

3. Add content

Add the following code in OnInitDialog()

CMFCPropertyGridProperty* pProp2 = new CMFCPropertyGridProperty(
        _T("choose"),
        _T("select"),
        _T(""));
pProp2->AddOption(_T("1"));
pProp2->AddOption(_T("2"));
pProp2->AddOption(_T("3"));
pProp2->AllowEdit(FALSE);  //Editing of options is not allowed

m_propertyGrid.AddProperty(pProp2);

The three parameters passed in when calling the constructor are item name , default options and description text .

Also, you could add drop-down menu:

CMFCPropertyGridProperty* pProp2 = new CMFCPropertyGridProperty(
        _T("choose"),
        _T("select"),
        _T(""));
    pProp2->AddOption(_T("1"));
    pProp2->AddOption(_T("2"));
    pProp2->AddOption(_T("3"));
    pProp2->AllowEdit(FALSE);  //Editing of options is not allowed

    m_propertyGrid.AddProperty(pProp2);

In addition, there are three similar projects:

CMFCPropertyGridColorProperty * pProp3 = new CMFCPropertyGridColorProperty(
    _T("colour"), RGB(0, 111, 200));
m_propertyGrid.AddProperty(pProp3);

CMFCPropertyGridFileProperty * pProp4 = new CMFCPropertyGridFileProperty(
    _T("open file"), TRUE, _T("D:\\test.txt"));
m_propertyGrid.AddProperty(pProp4);

LOGFONT font = { NULL };
CMFCPropertyGridFontProperty * pProp5 = new CMFCPropertyGridFontProperty(
    _T("select font"), font);
m_propertyGrid.AddProperty(pProp5);

Finally, This is the final program running interface:
