SetTextL doesn't work!

[asadi.alireza]

hi there,

I've got a Label in my simple UI application, when I call SetTextL of the Label at run time, nothing changes!!
here you are my code :

void CTestUIContainer::setStatus(const TDesC& value){
	iLabel1->SetTextL(value);
}

And I call the above method from the CtestUIContainerView::HandleCommandL when a menu get selected as code below :

iTestUIContainer->setStatus(_L("Waiting..."));

by the way when I put the changing label code at the following method which runs at the initiate loading, it works:

void CTestUIContainer::LayoutControls()
	{
	iLabel1->SetExtent( TPoint( 0, 2 ), TSize( 235, 119 ) );
	iLabel1->SetTextL(_L("Started..."));
	}

does anyone know what is wrong with my code? :(

Try calling DrawNow() after changing the value.

Thanks for your prompt reply,

I have changed my code to the following one :

void CTestUIContainer::setStatus(const TDesC& value){
	iLabel1->SetTextL(value);
	DrawNow();
}

but doesn't work again... :(

Are you implementing the Count components etc. functions in the CTestUIContainer. so the system would know how many controls there are inside the container, and would also be able to get pointers for them to get them drawn correctly ?

how about this:

void CTestUIContainer::setStatus(const TDesC& value){
iLabel1->SetExtent( TPoint( 0, 2 ), TSize( 235, 119 ) );
	iLabel1->SetTextL(value);
	DrawNow();
}

should not really help if ComponentControl(TInt) & CountComponentControls() functions are not implemented in the container.

should not really help if ComponentControl(TInt) & CountComponentControls() functions are not implemented in the container.

but i think the label wouldn't be visible first time as well if these functions are not implemented.

should not really help if ComponentControl(TInt) & CountComponentControls() functions are not implemented in the container.

yes, I've got the mentioned methods in Container :

/**
* Return the number of controls in the container (override)
* @return count
*/
TInt CTestUIContainer::CountComponentControls() const
	{
	return ( int ) ELastControl;
	}
				
/**
* Get the control with the given index (override)
* @param aIndex Control index [0...n) (limited by #CountComponentControls)
* @return Pointer to control
*/
CCoeControl* CTestUIContainer::ComponentControl( TInt aIndex ) const
	{
	// [[[ begin generated region: do not modify [Generated Contents]
	switch ( aIndex )
		{
		case ELabel1:
			return iLabel1;
		}
	// ]]] end generated region [Generated Contents]
	
	// handle any user controls here...
	
	return NULL;
	}

[vineet.jain]

have you implemented the SizeChanged() method ?

[asadi.alireza]

It doesn't work either :(((((

how about this:

void CTestUIContainer::setStatus(const TDesC& value){
iLabel1->SetExtent( TPoint( 0, 2 ), TSize( 235, 119 ) );
	iLabel1->SetTextL(value);
	DrawNow();
}

I've found a point,

just after changing the label I place a socket accept implementation :

			iTestUIContainer->setStatus(_L("Waiting..."));

			RSocket acceptSock;
			User::LeaveIfError(acceptSock.Open(iSocketServ));
			iSocket->Accept(acceptSock, aStatus);
			User::WaitForRequest(aStatus);

:

when I remove the socket part(the red part), it works correctly and change the label, any clue why it behaves this way??!!! and why i cannot change the label when I am waiting for a incoming socket???!!!
