< | < | ||
- | Use the SetOnTouch and SetOnLongTouch methods of the List object to set the name of a function you want to be called when a list item is selected. The selected item is passed into your OnTouch callback function as a parameter every time an item is selected or long touched. | + | Use the **SetOnTouch** and **SetOnLongTouch** methods of the List object to set the name of a function you want to be called when a list item is selected. The selected item is passed into your OnTouch callback function as a parameter every time an item is selected or long touched. |

+ | ====Example - Simple==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | lst = app.CreateList( " | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lst.SetOnLongTouch( lst_OnLongTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( "Item = " + item, " | ||
+ | } | ||
+ | function lst_OnLongTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( "Long Touch = " + item, " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | You can change the look of a List using the **SetBackColor** and **SetTextColor** functions on the list object. You can also set a background image/ | ||
+ | |||
+ | ====Example - Gray on white==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | lst = app.CreateList( " | ||
+ | lst.SetTextColor( "# | ||
+ | lst.SetBackColor( "# | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | The List object also supports **multi-line** list items and can show certain types of **icon**. Multi-line items are created by dividing each list item up using the ':' | ||
+ | |||
+ | You can have one icon and up to three lines of text using the following formats: | ||
+ | |||
+ | * title : icon | ||
+ | * title : body : icon | ||
+ | * title : body : extra : icon | ||
+ | |||
+ | The available icons types are displayed using the following key words: | ||
+ | |||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | |||
+ | You can also use the images on your sdcard, for example:- | ||
+ | |||
+ | " | ||
+ | |||
+ | |||
+ | ====Example - Title + Icon==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | var data = " | ||
+ | lst = app.CreateList( data, 0.8, 0.4 ); | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | ====Example - Title + Body==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | var data = "The Hobbit: | ||
+ | data += ", | ||
+ | lst = app.CreateList( data, 0.8, 0.4 ); | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | You can also create lists items that look like **buttons** by using one of the following options: | ||
+ | |||
+ | * " | ||
+ | * " | ||
+ | * " | ||
+ | |||
+ | ====Example - Orange Buttons==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | var data = " | ||
+ | lst = app.CreateList( data, 0.8, 0.8, " | ||
+ | lst.SetBackColor( "# | ||
+ | lst.SetPadding( 0.1, 0.1, 0.1, 0.1 ); | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | Or create lists with **Gradient** backgrounds like this: | ||
+ | |||
+ | ====Example - Gradient Background==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | var data = ""; | ||
+ | for( var i=1; i<=30; i++) | ||
+ | { | ||
+ | if( i>1 ) data += ","; | ||
+ | data += "Item " | ||
+ | } | ||
+ | lst = app.CreateList( data, 1, 1, " | ||
+ | lst.SetTextColor1( "# | ||
+ | lst.SetTextColor2( "# | ||
+ | lst.SetTextMargins( 0.04, 0, 0, 0 ); | ||
+ | lst.SetOnTouch( lst_OnTouch ); | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | app.AddLayout( lay ); | ||
+ | } | ||
+ | |||
+ | function lst_OnTouch( item ) | ||
+ | { | ||
+ | app.ShowPopup( " | ||
+ | } | ||
+ | </ | ||
+ | |||
+ | |||
+ | ====Example - HTML Font Color==== | ||
+ | <code javascript> | ||
+ | function OnStart() | ||
+ | { | ||
+ | // | ||
+ | lay = app.CreateLayout( " | ||
+ | |||
+ | // | ||
+ | var data = | ||
+ | "< | ||
+ | "< | ||
+ | "< | ||
+ | lst = app.CreateList( data, | ||
+ | lay.AddChild( lst ); | ||
+ | |||
+ | // | ||
+ | app.AddLayout( lay ); | ||
+ | } | ||
