useTabs specifies the application behavior after pressing the Tab key at runtime.

in Lycia Theme Designer

 

Form XML code:

 

<element_name useTabs="true">

 

By default, the property is set to false and is absent from the form XML code. The property value will appear in the form XML code only once the property value is set to true.

 

 

Theme property filter XML code:

 

<DoStyleAction>

  <SetProperty>

    <PropertyPath>

      <PropertyName>UseTabs</PropertyName>

    </PropertyPath>

  </SetProperty>

</DoStyleAction>

 

Possible values: true, false

 

Default value: false

 

Associated containers, widgets and theme elements: TextArea

 

Associated 4gl syntax:

INPUT ↓

 

Associated ui methods:

setUseTabs ↓

getUseTabs ↓

 

Influence and behavior:

 

 

 

 

 

With INPUT, if useTabs is set to false, then after the Tab key is pressed, the application will move to another TextArea at runtime. Otherwise, a tab symbol will be created inside the current field:

At runtime, you can use ui methods to specify the application behavior at runtime:

 

LET widget_var = ui.<widget>.ForName("widget_id1")

CALL widget_var.setUseTabs(...)

DISPLAY widget_var.getUseTabs()

 

4gl code sample

DEFINE ta_1, ta_2 ui.TextArea

...

LET ta_1 = ui.TextArea.ForName("f1")

LET ta_2 = ui.TextArea.ForName("f2")

...

CALL ta_1.setUseTabs(0)

CALL ta_2.setUseTabs(1)

DISPLAY ta_1.getUseTabs()

DISPLAY ta_2.getUsetabs()
