    12 <concept id="GUID-58318BAB-2EC4-4C9E-A7CA-580E701EE54F" xml:lang="en"><title>Adding

    13 and removing toolbar items</title><prolog><metadata><keywords/></metadata></prolog><conbody>

    14 <p> Toolbar items are controls that derive from the <codeph>CCoeControl</codeph> base

    15 class. The floating toolbar can have only buttons (<xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknButton.html" format="application/java-archive"><codeph>CAknButton</codeph></xref>) if it is focusing. The number of buttons displayed in floating toolbar

    16 depends on the screen resolution in use. The fixed toolbar always has three

    17 buttons. </p>

    18 <p>You can define toolbar items either in the resource file or create them

    19 dynamically at runtime. </p>

    20 <p>If you define the items in resources, use the <codeph>TBAR_CTRL</codeph> structure.

    21 Define at least the type, ID, and the control itself in this structure. For

    22 the resource definitions, see <xref href="GUID-402C3EE7-8852-49B6-BE62-8588753FAC8F.dita">Constructing

    23 the toolbar</xref>.</p>

    24 <p>To add the items dynamically, use the toolbar functions as illustrated

    25 in the examples below.</p>

    26 <p>You can add items to a specific position in toolbar or as the last item

    27 in the toolbar. </p>

    28 <p>You can also remove toolbar items at runtime.</p>

    29 <p>The example below shows how to add a button dynamically as the last toolbar

    30 item.</p>

    31 <codeblock xml:space="preserve">

    32 void CMyAppView::AddItemAsLastToToolbarL()

    33     {

    34     CAknToolbar* toolbar = Toolbar();

    35     if ( toolbar )

    36         {

    37         CAknButton* newButton = CAknButton::NewL( R_MYAPP_BUTTON );

    38         toolbar->AddItemL( newButton, EAknCtButton, KButtonId, 0 );

    39         }

    40     }

    41 </codeblock>

    42 <p>The example below shows how to add a button dynamically as the first toolbar

    43 item.</p>

    44 <codeblock xml:space="preserve">

    45 void CMyAppView::AddItemAsFirstToToolbarL()

    46     {

    47     CAknToolbar* toolbar = Toolbar();

    48     if ( toolbar )

    49         {

    50         CAknButton* newButton = CAknButton::NewL( R_MYAPP_BUTTON );

    51         // Last parameter the index at where to add the button

    52         toolbar->AddItemL( newButton, EAknCtButton, KButtonId, 0, 0 );

    53         }

    54     }

    55 </codeblock>

    56 <p>The example below shows how to remove a button from the toolbar based on

    57 the button ID.</p>

    58 <codeblock xml:space="preserve">

    59 void CMyAppView::RemoveItemFromToolbar()

    60     {

    61     CAknToolbar* toolbar = Toolbar();

    62     if ( toolbar )

    63         {

    64         toolbar->RemoveItem( KButtonId );

    65         }
