CXTPPropertyGridInplaceList - derivation.

Oleg,

I would like to be able to customise some of the functionality of the ListBox control in the PropertyGrid.

I do not understand how I am supposed to do this as the class construction makes this difficult to understand.

There are no examples that I can find in the Samples to help me with this.

I would appreciate some advice.

regards

Richard

Dear Oleg,

 As ever many thanks for your reply - I am able to continue with my development.

I have search for -: SetInplaceList

in the help/documentation but it is not documented. Please can you add it to the documentation list.

regards

Richard

ps. I am using ver 9.70

Standard List created with LBS_STRING style.

I suggest you to change logic something like:

CStyleItem::CStyleItem( CString _Caption )
 : CXTPPropertyGridItem( _Caption )
{
 m_nFlags = xtpGridItemHasComboButton;
 m_StyleList.m_pItem = this;

 //SOLID epaisseur 1 a cause du system NT
 AddStyleItem(PS_SOLID,1);
 
 //Traits exotiques

 AddStyleItem( PS_DOT, 2 );
 AddStyleItem( PS_DASH, 2 );
 AddStyleItem( PS_DASHDOT, 2 );
 AddStyleItem( PS_DASHDOTDOT, 2 );

 //Ajouter les épaisseurs "SOLID" >1
 AddStyleItem( PS_SOLID, 2 );
 AddStyleItem( PS_SOLID, 3 );
 AddStyleItem( PS_SOLID, 4 );
 AddStyleItem( PS_SOLID, 5 );
 AddStyleItem( PS_SOLID, 7 );
 AddStyleItem( PS_SOLID, 9 );
 AddStyleItem( PS_SOLID, 11 );
}

void CStyleItem::AddStyleItem(int style,int epaisseur)
{
 // add a listbox item
 DWORD stockval = MAKELONG((style & PS_STYLE_MASK)|PS_GEOMETRIC, epaisseur);
 GetConstraints()->AddConstraint(_T("Item"), stockval);
}

to move items to constraints of Items.

and drawing:

void CStyleItemList::DrawItem ( LPDRAWITEMSTRUCT lpDrawItemStruct )
{
 CDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
 CXTPPropertyGridItemConstraint* p = (CXTPPropertyGridItemConstraint*)lpDrawItemStruct->itemDa ta;
 DWORD a = p->m_dwData;
