How to add Check box CheckedIcon and UncheckedIcon in a List Box list items Tab?

Jahidur
Participant
I created a List Box with 2 tabs, In the first tab I insert some text in every list item, and in the second tab, i want to add a check box where i can check and uncheck any list items. I use the SetOnTabItem method to add check box in list items. But the problem is when i select list items the check box gets visible only in that selected list item. But in other list items, the check box gets invisible. That's why i want to add an icon in those unselected list items where an icon will represent is that the list item check box is checked or unchecked. I used the SetTabItemIcon to do this but can't get an acceptable result. Here i share my code files to understand my approach to do this task.

Use SetTabItemIcon to draw a checkbox in a tab:

list.SetTabItemIcon( item, tabindex, DG::Icon( SysResModule, on ? DG::ListBox::CheckedIcon : DG::ListBox::UncheckedIcon) ;

Handle the ListBoxClicked event:

void TestListDialog::ListBoxClicked( const DG::ListBoxClickEvent& ev )
{
	if ( ev.GetSource() == &mi_list )
	{
		short pos = ev.GetMouseOffset().GetX();
		short beg = mi_list.GetTabFieldBeginPosition( m_table.check );
		short end = mi_list.GetTabFieldEndPosition( m_table.check );
		if (  pos > end || pos < beg )
			return;

		OnListBoxCheckClicked( ev.GetListItem() );
	}
}
