void CE32FrodoAppUi::DynInitMenuPaneL (  TInt  aResourceId,
CEikMenuPane *  aMenuPane
)  [private, virtual]
 

Dynamically initialises a menu pane. The Uikon framework calls this function, if it is implemented in a menus observer, immediately before the menu pane is activated. Typically this function should inquire the value of application data, and initialise menu items accordingly. This includes dimming menu items, changing their text, setting the state of checked items and radio buttons and dynamically adding items to a menu.

Parameters:
aResourceId Resource ID identifying the main menu pane to initialise.
aMenuPane In/out. Pointer to the menu pane.

void CE32FrodoAppUi::OpenFileL (  const TDesC &  aFileName  )  [private, virtual]
 

called by EIKON framework when user taps on e.g. Frodo snapshot files we could handle more types here if we want, for example prefs files, .d64 .d64.gz .t64 .t64.gz etc...

called by EIKON framework during application startup. The variable aDocumentName contains the name of the file that the user tapped on in shell.

Headline: Why does CMyAppUi::ProcessCommandParametersL() not seem to get called on V6 of the Symbian Platform? Category: Application architecture EPOC Release: ER6 KeyWords: Application architecture, Porting, ProcessCommandParametersL, Document, File names Report: Why does CMyAppUi::ProcessCommandParametersL() not seem to get called on V6 of the Symbian Platform? Answer:

This can often catch you out when porting code from ER5 to V6. The function:

TBool CMyAppUi::ProcessCommandParametersL(TApaCommand aCommand,TFileName& aDocumentName,const TDesC&)

on ER5 must be coded as:

TBool CMyAppUi::ProcessCommandParametersL(TApaCommand aCommand,TFileName& aDocumentName,const TDesC8& )

on V6 otherwise it will not get called.
