Footerbar

Description

The FooterBar control puts up to 5 buttons on the bottom of the form. Buttons can be text, an icon or both. When clicked, <FooterBarID>_onclick(choice) is called. The name of the button which is called is in choice. If the text of the button has a space in it, it is replaced by an underbar. For example, "Edit Text" will call onclick with "Edit_Text"

To add a control to your app, choose the control’s icon in the Toolbar, then position it on the Design Screen. Use the Property Editor to set the properties you need, then add functions to your code to respond to the events that come from the control: usually, just on click.

When clicked, two events are sent. Ignore the first one - it's an object. See sample code below.

To make a FooterBar with icons only, set iconPos to top and put an empty, comma separated string in items. (",,").

Once a button is selected, it will be highlighted. To remove the highlight of the first item, you can do this after the click is finished:

$("#FooterBar1_0").removeClass("ui-btn-active")

To do this in the click routine itself, do

Function FooterBar1_onclick(choice)
  If TypeName(choice)="object" Then Exit Function
  MsgBox "Button is " & choice
  SetTimeout("$('#FooterBar1_0').removeClass('ui-btn-active')",500)     'for 1. Button
  SetTimeout("$('#FooterBar1_1').removeClass('ui-btn-active')",500)     'for 2. Button
  SetTimeout("$('#FooterBar1_2').removeClass('ui-btn-active')",500)     'for 3. Button
  ....
  ....
End Function

Custom Icons

There are a few steps to using your own icon instead of the built in ones.

1. In the Properties Window, put 'custom' into the icon property. (In the picker, it's the gray circle in the 4th row).

2. Add your icon to the project. Dragging into the Project Explorer is fine. The icon should be 16x16.

3. Add this code to the styleheaders property in Project Properties:

#FooterBar1_1:after {background-image: url("icon_16x16.png")}

The first word should be the name of the control with a # in front of it.
