    <p>I know this is a basic c++ question, but may I know how can I call a function/pass value (elementId) from one class to another in bada using the friend function? </p> <p>In my form class, I have a listView and when the item in the listView has been clicked, I would like to pass the elementId to detailedForm to display info in the label (in detailedForm). In my form.h and .cpp I have included detailedForm.h, may I know how do I access the function in detailedForm to display the info? In form.h, I have also declared </p> <pre><code>friend class detailedForm; </code></pre> <p>and when I tried to use one of the function in detailedForm in my form class, namely displayInfo(); the form class has an error saying displayInfo() has not been declared. </p> <p>form.h</p> <pre><code>... public: friend class ChartFormDetail; </code></pre> <p>Here is my code for form.cpp</p> <pre><code>#include "Form.h" #include "ChartFormDetail.h" ... void Form::OnGroupedListViewItemStateChanged(Osp::Ui::Controls::GroupedListView &amp;listView, int groupIndex, int itemIndex, int elementId, Osp::Ui::Controls::ListItemStatus state) { Frame* pFrame = Osp::App::Application::GetInstance()-&gt;GetAppFrame()-&gt;GetFrame(); FormMgr* pFormMgr = dynamic_cast&lt;FormMgr*&gt; (pFrame-&gt;GetControl("FormMgr")); if(pFormMgr == null) return; pFormMgr-&gt;SendUserEvent(FormMgr::REQUEST_DETAILFORM, null); //pFormMgr-&gt;SendUserEvent(elementId, null); switch(elementId) { case ID_FORMAT_STRING_M12: DisplayLabel(); break; ... case ID_FORMAT_STRING_F19: DisplayLabel(); break; } } </code></pre> <p>detailedForm.h</p> <pre><code>public: ... void DisplayLabel(void); </code></pre> <p>code for detailedForm.cpp</p> <pre><code>void ChartFormDetail::DisplayInfo(void) { pLabel-&gt;SetText("Text here"); RequestRedraw(); } </code></pre>

    3. COYou say the error happens when calling `displayInfo`, but there is no call to `displayInfo` in the code you posted.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
