CDialog as property-grid item

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

finally I have implemented a class, that embeds a CDialog into a
property-grid item. One can see the result in the GridSample-based
demo-project: 2005-11-22_023757_GridSampleForum.zip

The new item is a CXTPPropertyGridItem-derived class, which holds a pointer
to CDialog as a member. In the constructor the CDialog will be created,
whereas OnDrawItemValue only shows or hides the dialog via ShowWindow.
It also uses a pointer to the grid for resizing the grid automatically,
if the dialog to be embed is wider than the grid. Caution: the MFC
limits the height of a CListBox-item to 255 pixel (CXTPPropertyGrid is
a CListBox derived class). Dialogs that are higher will be cropped.
Last but not least one has keyboard navigation. (To leave the inplace
dialog press ESC.)

I only have a problem with correct drawing of the dialog. Maybe someone
can take a look at the code and give me a hint why the drawing is
incorrect. (There is a problem with the scrollbars, too but Oleg told
me that this must be a CListBox-bug and he will try to find a
workaround. Maybe in 9.81 everything works fine.)

Best regards

   Holger

	Hello, I am developing a property-grid item that holds a CDialog. (I know this is a little bit perverse but my boss wants it;-) At the moment I have some problems with correct drawing of the CDialog, especially when expanding/collapsing other categories of the grid the inplace dialog will not be drawn correctly. I have overridden the OnDrawItemValue member of my inplace-dialog class in nearly the same manner as shown for the button-property in the GridSample but the function will not get called, when the whole item gets invisible due to expanding an other category. So my inplace dialog stays visible:-( Anyone can give me a hint on how to handle this problem? Best regards, Holger
