Split windows, load tree controls for one of them? ? ?

2317976

Thanks to my colleagues who saw this question, the questions are as follows:
SDI is divided into 1 row and 2 columns, two windows; how do I load a tree control for one of the windows dynamically?

I tried direct Creat, but it doesn't work, the code is as follows:

m_TreeCtrl.Create (TVS_CHECKBOXES | TVS_EDITLABELS | TVS_FULLROWSELECT |
TVS_HASBUTTONS | TVS_HASLINES | TVS_INFOTIP | TVS_SHOWSELALWAYS, rect, pCwnd, IDC_MYTREE);


bool CMainFrame :: InitTree (void)
{
          ...
          ...
}

The tree can be dynamically increased in the OnCreate of the view, or directly use a CTreeView

CRect rectDummy;
rectDummy.SetRectEmpty();

// Create view
const DWORD dwViewStyle = WS_CHILD | WS_VISIBLE | TVS_HASLINES |
TVS_LINESATROOT | TVS_HASBUTTONS | WS_CLIPSIBLINGS |
WS_CLIPCHILDREN;

if (!m_wndTree.Create(dwViewStyle, rectDummy, this, 2))
{
TRACE0 ("Failed to create view\n");
return -1; // fail to create
}

The style of the control should be visible and be a child window. WS_CHILD | WS_VISIBLE, or drag it directly with CTREEVIEW or CFORMVIEW.

A class derived from CTreeView, such as CLeftView, can display tree controls.


Add a member in the CMainFrame class
CSplitterWnd m_wndSplitter;

Implement CMainFrame::OnCreateClient() method, part of the code:
    // TODO: create split view
if (!m_wndSplitter.CreateStatic(this, 1, 2))
{
TRACE0("Failed to CreateStaticSplitter\n");
return FALSE;
}
// add-an input view in column 1
if (!m_wndSplitter.CreateView(0, 0,
RUNTIME_CLASS(CLeftView), CSize(170, 0), pContext))
{
TRACE0("Failed to create second pane\n");
return FALSE;
}
         // Add another view using the same method
// activate the input view
SetActiveView((CView*)m_wndSplitter.GetPane(0,1));

When creating a project directly, create a resource manager type window, which will automatically split the window, and then dynamically create a tree in CLeftView.

Try this, take him as the parent window in one of the windows, create a non-modal dialog box, and then you can do whatever you want on it^_^

Visual Graph is a powerful interactive graphic development platform. It can easily build graphic-based interfaces, make various graphic elements, realize graphic management, graphic modeling, production monitoring system, form system, drawing system, process design, CAD software, etc. She provides very powerful ActiveX controls and works with other popular programming languages, which greatly compensates for the lack of graphics processing of these languages. It can also be embedded in IE browser to realize online graphic editing and control. http://www.visual-graph.com
