How to add check boxes to List Box?

Hi,
Please tell me if it is possible to add checkboxes to the List Box?
I have a lot of categories that I want to group in a List Box. These categories are selected through standard checkboxes. Is it possible to add them in this form to the List Box?

Hi, the best way to show checkboxes on the listbox lines is to set the special icons defined in DGListBox.hpp with the ListBox::SetTabItemIcon (short listItem, short tabIndex, const DG::Icon& icon) member function. You can use these type of check icons:

enum SpecialIcons { NoIcon = DG_NO_ICON, DragIcon = DG_LIST_DRAGICON, CheckedIcon = DG_LIST_CHECKEDICON, UncheckedIcon = DG_LIST_UNCHECKEDICON, MixedCheckedIcon = DG_LIST_MIXEDCHECKEDICON, GrayCheckedIcon = DG_LIST_GRAYCHECKEDICON, GrayUncheckedIcon = DG_LIST_GRAYUNCHECKEDICON, GrayMixedCheckedIcon = DG_LIST_GRAYMIXEDCHECKEDICON, FramelessCheckIcon = DG_LIST_FRAMELESSCHECKICON, FramelessGrayCheckIcon = DG_LIST_FRAMELESSGRAYCHECKICON };

Whenever the data changes, the corresponding icon should be set on the tabfield.

On a click event the dialog can determine from the click position whether the icon was clicked or not.

Here is an example:

list.SetTabItemIcon (rowIndex, checkColumn, DG::Icon (SysResModule, DG::ListBox::CheckedIcon));

Putting a checkbox item on the list row with the SetOnTabItem member function is not advised, because the checkbox controls have some background colored frame around which result a bit ugly lookout.
