| MenuLayer | | public class MenuLayer extends ScrollablePopupLayer (Code) | | A special popup layer which implements a system
menu. The system menu is a collection of commands,
both screen (Back, Exit, etc) and item specific
commands.

| btnLayer | | protected SoftButtonLayer btnLayer(Code) | | The SoftButtonLayer maintains the overall set of
commands and their associated listeners.
|
| cascadeMenu | | protected CascadeMenuLayer cascadeMenu(Code) | | A cascading menu which holds commands for a SubMenuCommand.
|
| cascadeMenuUp | | protected boolean cascadeMenuUp(Code) | | A flag indicating if a cascading menu is visible.
|
| menuCmds | | protected Command[] menuCmds(Code) | | The list of Commands to display in the menu.
|

|
| MenuLayer | | public MenuLayer()(Code) | | Construct a new system menu layer.
|
| alignMenu | | protected void alignMenu()(Code) | | Aligns the menu to the current screen.
|
| dismiss | | public void dismiss()(Code) | | Cleans up the display when the cascaded menu is dismissed.
Removes the layer with the menu and requests the display to be
repainted.
|
| dismissCascadeMenu | | public void dismissCascadeMenu()(Code) | | Cleans up the display when the cascaded menu is dismissed.
Removes the layer with the menu and requests the display to be
repainted.
|
| getIndex | | public int getIndex()(Code) | | Gets index of highlighted command.
highlighted index |
| initialize | | protected void initialize()(Code) | | Initializes the menu parameters.
|
| keyInput | | public boolean keyInput(int type, int keyCode)(Code) | | Handles key input from a keypad. Parameters describe
the type of key event and the platform-specific
code for the key. (Codes are translated using the
lcdui.Canvas)
Parameters:
type - the type of key event
Parameters:
keyCode - the numeric code assigned to the key true if the input has been processed by thismethod, otherwise false (soft menu keys) |
| paintBody | | protected void paintBody(Graphics g)(Code) | | Renders the body of the menu.
Parameters:
g - the graphics context to be updated |
| pointerInput | | public boolean pointerInput(int type, int x, int y)(Code) | | Handle input from a pen tap. Parameters describe
the type of pen event and the x,y location in the
layer at which the event occurred. Important : the
x,y location of the pen tap will already be translated
into the coordinate space of the layer.
Parameters:
type - the type of pen event
Parameters:
x - the x coordinate of the event
Parameters:
y - the y coordinate of the event |
| setMenuCommands | | public void setMenuCommands(Command[] cmdList, SoftButtonLayer btnLayer, int index)(Code) | | Called typically by the SoftButtonLayer to establish the
set of Commands to display on this system menu. This method will
create a new copy of the array of commands passed in.
Parameters:
cmdList - the set of commands to display in the menu(the commands should already be sorted by priority)
Parameters:
btnLayer - the SoftButtonLayer to notify of any commandselections
Parameters:
index - the command index has to be highlighted. If index exceedsthe number of commands the 1st command has to be highlighted. |
| subCommandSelected | | public void subCommandSelected(Command cmd)(Code) | | Notifies listener that a command has been selected.
Dismisses the cascaded menu and the button layer.
Parameters:
cmd - the command that was selected |
| uScrollAt | | void uScrollAt(int position)(Code) | | Perform a scrolling at the given position.
Parameters:
context - position |
| update | | public void update(CLayer[] layers)(Code) | | Update bounds of layer
Parameters:
layers - - current layer can be dependant on this parameter |
| updateScrollIndicator | | public void updateScrollIndicator()(Code) | | Updates the scroll indicator.
