Tree-列表树元素

Tree 树元素

树元素.

• XE_TREE_SELECT :树项选择事件.
• XE_TREE_EXPAND :树项展开收缩事件.

步骤:

1. XTree_Create()创建树元素.

#pragma comment(lib, "XCGUI.lib")
#include "xcgui.h"
 
HWINDOW  hWindow = NULL;
int APIENTRY _tWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
    XInitXCGUI(TRUE); //初始化
    hWindow = XWnd_Create(0, 0, 600, 400, L"炫彩界面库-窗口");//创建窗口
    if (hWindow)
    {
        HELE hTree = XTree_Create(20, 40, 500, 300, hWindow);
        XTree_SetItemTemplateXML(hTree, L"XML-template\\ListBox_Item.xml");
        XTree_CreateAdapter(hTree);
 
        wchar_t buf[MAX_PATH] = { 0 };
        for (int i = 0; i < 10; i++)
        {
            wsprintf(buf, L"item-%d", i + 1);
            int index = XTree_InsertItemText(hTree, buf);
            XTree_SetItemText(hTree, index, 1, L"subitem-1");
            XTree_SetItemText(hTree, index, 2, L"subitem-2");
        }
 
        XWnd_ShowWindow(hWindow, SW_SHOW);//显示窗口
        XRunXCGUI(); //运行
    }
    XExitXCGUI(); //释放资源
    return 0;
}
