ComboBox-下拉组合框元素

ComboBox下拉组合框元素

下拉组合框元素,点击下拉按钮,弹出下拉列表,选择项更改内容.

• XE_COMBOBOX_POPUP_LIST :组合框下拉列表弹出事件
• XE_COMBOBOX_SELECT :组合框下拉列表中项选择事件.
• XE_COMBOBOX_EXIT_LIST :组合框弹出下拉列表关闭事件

步骤:

1. XComboBox_Create()创建下拉组合框元素.
2. XComboBox_SetDropHeight()设置下拉列表高度.
3. XComboBox_SetSelItem()设置选择项.

#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, 300, 300, L"炫彩界面库-窗口");//创建窗口
    if (hWindow)
    {
        HELE hComboBox = XComboBox_Create(20, 40, 200, 30, hWindow);
        XComboBox_SetItemTemplateXML(hComboBox, L"xml-template\\ComboBox_ListBox_Item.xml");
        XComboBox_CreateAdapter(hComboBox);
        XEdit_SetText(hComboBox, L"123");
 
        wchar_t buf[MAX_PATH] = { 0 };
        for (int i = 0; i < 10; i++)
        {
            wsprintf(buf, L"item-%d", i + 1);
            int index =XComboBox_AddItemText(hComboBox, buf);
            XComboBox_SetItemText(hComboBox, index, 1, L"subitem-1");
            XComboBox_SetItemText(hComboBox, index, 2, L"subitem-2");
        }
 
        XWnd_ShowWindow(hWindow, SW_SHOW);//显示窗口
        XRunXCGUI(); //运行
    }
    XExitXCGUI(); //释放资源
    return 0;
}
