HowTo: Use a Progress Indicator in a Panel

The purpose of this article is to explain the necessary steps to enable the Progress Indicator User Control in Panels.

Scope

Objects: Panel, Procedure, Work With
Generators: Android, Apple

Step 1. External Object - Properties and Methods

See Progress Indicator User Control in order to understand the API of the user control.

Step 2. Learn by Example

Use a Procedure with the Sleep function set to 4 in order to simulate an elapsed time.

For this example, create the following Panel:

Layout

Events

Event 'Determinate'
    Composite
        Progress.Type = ProgressIndicatorType.Determinate
        progress.MaxValue = 100
        progress.Value = 0
        Progress.ShowWithTitleAndDescription("ProcessDeterminate","Sleeping...")
        sleepingProc()
        Progress.Value =25
        sleepingProc()
        Progress.Value =50
        sleepingProc()
        Progress.Value =75
        sleepingProc()
        Progress.Value =100
   EndComposite
EndEvent

Event 'Indeterminate'
    Composite
        Progress.Title = "Process Indeterminate"
        Progress.Description = "Sleeping..."
        Progress.Class = "Table.Progress"
        Progress.Type = ProgressIndicatorType.Indeterminate
        Progress.Show()
        sleepingProc()
   EndComposite
EndEvent

Facts: (In Evolution 2 Upgrade 2)

• At the end of an Event an implicit Hide() is done. this is in case the Hide() call hasn't been done by the user.
• The scope of the properties of a Progress Indicator is per Panel. So, if calls are done between two Panels which have a Progress Indicator the properties are not going to be shared.
• Any UI element invoked by an action which also has a call to the Progress Indicator will be shown over the progress Indicator (Call, MSG, Confirm, etc).

Step 3. Execution

Determinate

     

Indeterminate

Restrictions

• The Progress Indicator external object can only be called from client-side events of Panels and from offline Procedures objects.
