I have a TabControl (NormalTab) which has two tab

I have five classes to implement my TabControl
There is one main dialog class and two class for each tab.

My dialog opens without any problem. First tab events fires without any problem. The only problem is that second tab events (ButtonClicked) do not fire and I can not change any control text in second tab.

Here is my whole code.

Hi,

There could be more bugs in your code, but the first I noticed is the following:
You should have an observer class for your modaldialog also (ExportDialogObserver), so 2 class for each.
And the modaldialog's observer should be inherited from DG::PanelObserver, DG::NormalTabObserver and DG::CompoundItemObserver.

It's a mistake in your code that your tabpages' observers inherited from DG::NormalTabObserver, however they don't have any NormalTab, so please delete that inheritance.

Regards,
Tibor

Than you for the response.

What concern to tabpage's observers I removed the DG::NormalTabObserver.

The strange thing is that first tab functionality working fine. The only problem is second tab.

What concern ModelDialog why I should have an observer class ?

Some times age you gave me this example where the main dialog has no observer

And why I need Observer also for Dialog ?
Observers handle the user interface changes. So if the user selects an another tab, then the observer must handle it and run the required updates.
In your case I think one of the required updated didn't run and that's why you should implement an observer for your dialog class, and attach the observer to the dialog.

I added also Dialog's observer but the result is the same

The strange thing is that my second tab constructor working and in constructor I wrote this this->m_btnCancel.SetText("ascaca"); which does not change the button name.

Here is the new dialog's observer class
Code: Select all

class TabControlObserver:   public DG::PanelObserver, 
               public DG::NormalTabObserver, 
               public DG::ButtonItemObserver, 
               public DG::CompoundItemObserver 
{ 
private: 
   ExportDialog*      mDialog; 

protected: 
   // DG::PanelObserver 
   virtual void   PanelOpened (const DG::PanelOpenEvent& ev) override; 

   // DG::ButtonItemObserver 
   virtual void   ButtonClicked (const DG::ButtonClickEvent& ev) override; 

public: 
   explicit      TabControlObserver (ExportDialog* testDialog); 
   ~TabControlObserver (); 
}; 

.cpp
Code: Select all
TabControlObserver::TabControlObserver (ExportDialog* testDialog): 
   mDialog (testDialog) 
{ 
   mDialog->Attach (*this); 
   AttachToAllItems (*mDialog); 
} 


TabControlObserver::~TabControlObserver () 
{ 
   mDialog->Detach (*this); 
   DetachFromAllItems (*mDialog); 
} 


void TabControlObserver::PanelOpened (const DG::PanelOpenEvent& /*ev*/) 
{ 
   mDialog->SetClientSize (mDialog->GetOriginalClientWidth (), mDialog->GetOriginalClientHeight ()); 
} 


void TabControlObserver::ButtonClicked (const DG::ButtonClickEvent& ev) 
{ 
   
} 

And I'm calling the dialog by this way
Code: Select all
ExportDialog      dialog (ACAPI_GetOwnResModule (), 32511); 
   
	if (DBERROR (dialog.GetId () == 0)) { 
		return; 
	} 
  
	TabControlObserver      observer (&dialog); 
	dialog.Invoke (); 
	return;
