},
This is a control without a prompt or control ID (neither are needed). The control is a label.
You should always use the annotation font for cue text labels.
The other controls use an EDWIN and CHOICELISTs, which we've already met. The derived
dialog class shows the functions we use to control the visibility of the address field:
class CGameInitiateDialog : public CEikDialog
{
public:
CGameInitiateDialog(CGameController* aController);
private:
// From CEikDialog
void PreLayoutDynInitL(); // Settings on dialog launch
TBool OkToExitL(TInt aKeycode); // Action when OK pressed
// Listen to changing selections
void HandleControlStateChangeL(TInt aControlId);
// Show only necessary controls
void ShowRelevantControls(); // Called when needed
private:
CGameController* iController;
};
As well as PreLayoutDynInitL() and OkToExitL(), I have implemented another
CEikDialog framework function, HandleControlStateChangeL(), which gets called
with the relevant control ID whenever the value of any of the choice list fields in the dialog is
changed. I also have a function called ShowRelevantControls() that I use to show or
hide the address depending on the settings of other controls.
Here's the implementation of ShowRelevantControls():
void CGameInitiateDialog::ShowRelevantControls()
{
CEikChoiceList* choicelist1 =
static_cast(Control(EGameControlIdStartMode));
CEikChoiceList* choicelist2 =
static_cast(Control(EGameControlIdProtocol));
// Get start mode: 1=listen, 0=initiate
TInt listen = choicelist1->CurrentItem();
// Get protocol
