Parameters

Return Value

GetLastEventType returns the type of the last event received. If no events have been triggered, GetLastEventType returns WS_EVENT_INVALID.

Remarks

The available event types are:

• WS_EVENT_CLICK: This event is triggered when a widget is clicked. The widgets that can trigger this event are: WS_BUTTON, WS_CHECKBOX, WS_LIST_CTRL, WS_MENU and WS_RADIO_BUTTON.
• WS_EVENT_TEXT_INPUT: Triggered only by the WS_FIELD widget. This event is received when the user inputs a text and press the ENTER key or reads a barcode with the scanner.
• WS_EVENT_TEXT_SUBMIT: Triggered only by the WS_FIELD widget when the client configuration is modified to do so, see EnableSubmitMode for more information. This event is received when a widget who is using the submit mode, forces the WS_FIELD to trigger is input event.
• WS_EVENT_FUNCTION_KEY: Triggered when one of the function keys is pressed: F1-F20, arrows (if they're mapped) or ESC. This event is triggered by an special widget, the Function Keys controller.

Example

using WirelessStudioOleWidgets;
WStFactory oFactory = new WStFactory();
WStForm oForm = new WStForm ();
short formId = 10;
oFactory.CreateFormById(formId);
oForm.ShowById(formId, true, true);

if(oForm.GetEvent() && oForm.GetLastEventType() == (short)WSTEventTypes.WS_EVENT_FUNCTION_KEY)
{
  //Add your code here...
}

Public wsForm As New WStForm
...
bResult = wsForm.ShowByName("myForm", True, True)
'Waits for an event and performs an action
While (bEnd = False And bResult)
	bResult = wsForm.GetEvent()
	If wsForm.GetLastEventType() = WS_EVENT_TEXT_INPUT Then
		'Add your code here...
	End If
Wend
