-control stack</title><prolog><metadata><keywords/></metadata></prolog><conbody>
-<p>The control stack is a mechanism provided by the control framework for
-handling key press events. The Window Server, which generates events for control
-framework applications, channels all key press events to the application that
-currently has keyboard focus (Strictly speaking it channels key press events
-to the <keyword>window group</keyword> ). It is up to the application itself
-to channel the event to the correct destination as the Window Server does
-not associate a key press event with a particular control. </p>
-<p>In control framework applications using the <keyword>standard app     
-   UI</keyword> the control stack contains a list of controls that wish to
-receive keyboard events. Controls are added to the stack using <codeph>CCoeAppUi::AddToStackL()</codeph> and
-their ordering on the stack determines their priority in receiving key events:
-The one with the lowest position on the stack receiving key events first.
-When a key press event occurs, it is offered to each control on the stack
-in turn until it is consumed (i.e. used by that control). </p>
-<p>The ordering of controls on the stack is determined by their priority,
-a value passed to <codeph>CCoeAppUi::AddToStackL()</codeph>. If several controls
-on the stack have the same priority, their ordering is determined by the order
-in which they were added to the stack. </p>

-<p>The diagram below shows a hypothetical stack containing 4 controls added
-in the following order: control A (priority <codeph>ECoeStackPriorityDialog</codeph>),
-control B (<codeph>ECoeStackPriorityMenu</codeph>), control C (<codeph>ECoeStackPriorityDefault</codeph> —
-used for application views) and control D (<codeph>ECoeStackPriorityDialog</codeph>). </p>

-<p>On the stack shown in the diagram key-press events will be offered first
-to control D, followed by A, B and C in that order. A control on the stack
-can refuse key press events by setting a flag. This might be done by a dialogs
-when it is not visible. </p>
-<p>Applications use the control stack to channel key press events to destinations
-in decreasing order of priority, such as: </p>
