The following code snippet demonstrates how to append selected categories to the specified landmark

It is necessary to include the following headers:

   * clmkcategoryselectordlg.h
   * tlmkitemiddbcombiinfo.h

And link against:

   * lmkcommonui.lib 
   * eposlandmarks.lib 
   * lbs.lib
CPosLandmark* lm = ... // specify your landmark
 
// prepare dialog
CLmkCategorySelectorDlg * selectCategoriesDlg = CLmkCategorySelectorDlg :: NewL( ETrue );
selectCategoriesDlg->SetMopParent( this );
RArray< TLmkItemIdDbCombiInfo > arrCategories;
CleanupClosePushL( arrCategories );
 
// select array of categories
if( selectCategoriesDlg->ExecuteLD( arrCategories ) != 0 )
{
for( int i = 0; i < arrCategories.Count(); i++ )
{
// get current category ID
TPosLmItemId categoryId = arrCategories[ i ].GetItemId();
if( categoryId != KPosLmNullItemId )
lm->AddCategoryL( categoryId );
}
delete arrCategories[0].GetLmDb(); // fixing memory leak
}
CleanupStack::PopAndDestroy(); // arrCategories


And the following code snippet demonstrates how to remove all categories from the specified landmark:

CPosLandmark* lm = ... // specify your landmark
 
RArray< TPosLmItemId > categories;
// read all landmark categories
lm->GetCategoriesL( categories );
for( int i = 0; i < categories.Count(); i++ )
{
TPosLmItemId categoryId = categories[ i ];
// remove current category
lm->RemoveCategory( categoryId );
}
categories.Close();
