ScrollView-滚动视图元素

ScrollView 滚动视图元素

滚动视图元素,具有水平滚动条和垂直滚动条,可以左右上下滚动视图.

• XE_SCROLLVIEW_SCROLL_H :滚动视图水平滚动事件.
• XE_SCROLLVIEW_SCROLL_V :滚动视图垂直滚动事件.

步骤:

1. XSView_Create()创建滚动视图元素.
2. XSView_SetTotalSize()设置视图内容大小,也就是可以滚动的最大区域.

示例代码:

#pragma comment(lib, "XCGUI.lib")
#include "xcgui.h"
 
class CMyWindowScrollView
{
public:
    HWINDOW m_hWindow;
    HELE    m_hScrollView;
    CMyWindowScrollView()
    {
        Init();
    }
    void Init()
    {
        m_hWindow = XWnd_Create(0, 0, 300, 300, L"炫彩界面库窗口", NULL, window_style_default);
 
        m_hScrollView=XSView_Create(20,50,200,200,m_hWindow);
        XSView_SetTotalSize(m_hScrollView,300,300);
        XBtn_Create(10,10,100,20,L"Button1",m_hScrollView);
        XBtn_Create(10,40,100,20,L"Button2",m_hScrollView);
        XBtn_Create(10,70,100,20,L"Button3",m_hScrollView);
 
        XEle_RegEventCPP(m_hScrollView,XE_SCROLLVIEW_SCROLL_H,&CMyWindowScrollView::OnScrollViewScrollH);
        XEle_RegEventCPP(m_hScrollView,XE_SCROLLVIEW_SCROLL_V,&CMyWindowScrollView::OnScrollViewScrollV);
        XWnd_ShowWindow(m_hWindow,SW_SHOW);
    }
    int  OnScrollViewScrollH(int pos,BOOL *pbHandled)
    {
        XTRACE("XE_SCROLLVIEW_SCROLL_H %d \n",pos);
        return 0;
    }
    int  OnScrollViewScrollV(int pos,BOOL *pbHandled)
    {
        XTRACE("XE_SCROLLVIEW_SCROLL_V %d \n",pos);
        return 0;
    }
};
 
int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPTSTR lpCmdLine, int nCmdShow)
{
    XInitXCGUI(TRUE);
    CMyWindowScrollView  MyWindow;
    XRunXCGUI();
    XExitXCGUI();
    return TRUE;
}
