Toolbox objects
Creating objects
Objects are created (in the application's program) using the SWI
SYS &44EC0,,"MyTemplate" TO object
or its veneer equivalent
object=FNToolbox_CreateObject("MyTemplate")
Either of these commands creates an object from the template whose name is MyTemplate. The variable object, whose value is assigned by the Toolbox, is a 32-bit integer known as the object's id. If the template's 'Shared object' flag is set (see below) then only one object can be created with only one object id; otherwise a new object id is assigned each time the template is used.
Showing an object
To show an object on the desktop call
SYS&44EC3,,object,showtype
or its veneer equivalent
PROCToolbox_ShowObject(object,showtype)
where object is the object id and showtype is a parameter indicating how the object is to be shown.
Automatically creating and showing objects
If a template's Auto-create and Auto-show flags are set then an object of that type will be automatically created and shown on the desktop (without the need to write any code).
Setting a template's auto-show and auto-create flags
N.B. When a new AppBasic application is created the iconbar object has its Auto-show and Auto-create flags set.
Attached objects
Objects can be attached to each other. For example, a menu can be attached to an iconbar object (as is the case with a new AppBasic application). As the following figure demonstrates, attaching objects is very easy to do using ResEd.

The steps are:
- Double-click the Iconbar template (to display its edit dialogue box)
- In the section of the dialogue box marked “Select button”, select the 'Show object' option button
- Drag the template to be attached to the writable icon (to enter its name. Alternatively, just type the name of the template to be attached)
- Select the 'OK' action button to register the changes.
N.B. When an object is created, all of its attached objects are also created
