Using the Code

eGUI provides a CBarWidget used to implement this feature. It is easy to use using the following steps:

void CMainMenuView::TestBarWidget()
{
int nItems=8;
//Create a CBarWidget
CBarWidget* pBarWidget = new CBarWidget();
m_pBarWidget=pBarWidget;
//Listen to the CBarWidget's event
this->m_pBarWidget->GetEventModel()->AddListener(this->GetEventListener());
pBarWidget->SetBackgroundColor(RGB(216,233,226));
//Insert the CBarWidget into container.
this->m_pRootContainer->InsertWidget(pBarWidget);
WRect rc;
this->m_pRootContainer->GetRect(&rc);
rc.x=0;
rc.y=rc.dy-100;
rc.dy=150;
//Set Bar Widget's size, note which will be re-sized automatically if you add more items.
pBarWidget->SetRect(&rc);
//Use a for loop to add the CImageWidget as the item.
//note, the item can be any type widget.
char draw_cmd[128];
char img_fn[128];
CImageWidget* pImageWidget = NULL;
rc.dy=48;
rc.dx=48;
WRect rcW;
for(int i=0;i<nitems;i++) pimagewidget="new" />
