Also I tried to use overlay image to get the effect but failed.

You could try to use custom draw to change your fonts on selected items: http://msdn2.microsoft.com/en-us/library/bb775487(VS.85).aspx Here is an article using a list view and you could adapt this information to the tree view: http://www.codeproject.com/KB/combobox/lvcustomdraw.aspx Tom <wei.niu(a)gmail.com> wrote in message news:1f287960-2f36-4a4e-a96d-aa450a699fc7(a)34g2000hsf.googlegroups.com... > // clear cut state > TreeView_SetItemState( hwnd, hItemCut, 0, TVIS_CUT ) ; > > // set cut state > TreeView_SetItemState( hwnd, hItemCut, TVIS_CUT,TVIS_CUT ) ; > > When I cutted the item,its icon changed to dark.I hope it changes to a > little vague,just like windows explorer.I can change item's icon by > myself without setting TVIS_CUT state,but does it mean TVIS_CUT is > useless if I do that? > > Also I tried to use overlay image to get the effect but failed.

As my trouble is the treeview item's icon changed to a black square after I cutted it,I don't need redraw the item,I just need to set the item's icon through TreeView_SetItem.My question is: it looks like the function of setting item's state to TVIS_CUT is only changing the item's icon,so can I control how the icon would be changed?At least,I don't want it changed to be a black square.
From: Tom Serface on 24 Apr 2008 01:36 I've never been able to get TVIS_CUT to work that's why I was suggesting a possible alternative. Could be that there is something in that style that is or'ing the icon or something to try to dim it out and it just isn't working correctly. You may be able to try to draw the disabled tree items using something like in these articles: http://www.codeguru.com/Cpp/controls/treeview/misc-advanced/article.php/c633 http://www.codeproject.com/KB/tree/colortreectrl.aspx Tom <wei.niu(a)gmail.com> wrote in message news:abc871b8-7bd6-46da-b8e7-771d9f805289(a)z24g2000prf.googlegroups.com... > On 4$B7n(B23$BF|(B, $B2<8a(B8$B;~(B34$BJ,(B, "Tom Serface" <tom.nos...(a)camaswood.com> wrote: >> I haven't had much luck with that one either.

It looks like it's a bug of treeview.I will change the icon by myself. |
