I needed a listbox showing Icons and text strings in our Application. When I didn’t find any, I decided to create one. This List Box supports changing Icon for an item and removing the ImageList for the List Box at runtime.
How To Use It
To use this listbox class, simply drag a list box from the controls palette and drop it in the dialog Box. Set the properties Owner Draw style to Fixed or Variable, and with the Has Strings style checked.
Following are the steps to add a CIconListBox Class to a dialog:
- Add IconListBox.cpp and IconListBox.h to your project.
- Add include "IconListBox.h" to the
header file of your dialog class. - Use ClassWizard to add a member variable of
control type for the List Box. Then replace the CListbox type
with CIconListBox.
// in dialog.h //{{AFX_DATA(CIconLBDemoDlg) enum { IDD = IDD_ICONLBDEMO_DIALOG }; CIconListBox m_ListBox; //}}AFX_DATA
To set the ImageList, item text and/or Image, the overloaded public methods of CIconListBox Class are used:
int AddString(LPCTSTR lpszItem);
int AddString(LPCTSTR lpszItem, int iImg);
int InsertString(int iIndex, LPCTSTR lpszItem);
int InsertString(int iIndex, LPCTSTR lpszItem, int iImg);
void SetItemImage(int iIndex, int iImg);
inline void SetImageList(CImageList* pImgList = NULL)
{ m_pImageList = pImgList; }
In the demo application the Image list is set to List Box in the dialog’s OnInitDialog() function. InitImageLists() method is the Dialog class function which is used to create the Image List.
// TODO: Add extra initialization here
InitImageLists();
m_ListBox.SetImageList(&m_imgNormal);
