The parameters of a picture displayer are being configured in the palette Connect object through the following tabs.

Object

Connected object

An object of Picture type to display in the displayer. If an Inherited instance is checked, the instance number of the picture, opened in the displayer (subpicture), is the same as the instance of the parent picture (picture that contain this displayer). If it is inactive, the instance number may be entered directly into the Instance number. Checkbox Multiple open enables opening the subpicture of the same instance number in the multiple parent pictures simultaneously.

Inherited instance

If the parameter is checked, the instance number of the subpicture displayed in the displayer will be the same as the instance number of the picture.

Instance number

Instance number of the subpicture. The parameter is enabled if the parameter Inherited instance is not checked.

Multiple open

Multiple openings of the subpicture with the same instance number in several pictures.

Paint as transparent

If the parameter is checked, the background of the displayed scheme will be transparent.

Color palette

Allows you to set the color palette.

Script

Reference variable

Specifies the name of the displayer in the form of a reference variable for use in the picture script.

Metadata

Assignment of application data (metadata) to a graphic object. If the object contains some metadata, the name of the first record will be displayed on the button. Multiple records are indicated by ",...".

Event

The listbox allows the user to select an active picture event for the displayer. The listbox contains the following active picture events:

• OnClick
• OnMouseDown
• OnMouseEnter
• OnMouseLeave
• OnUserInput

Event Handler

The button opens the active picture script to define the active picture event specified by the parameter Event.

Note relating to D2000 Thin Client

The picture displayer does not allow the event handler (OnClick, etc.) as it is in D2000 HI.
For more rules see the page Drawing rules and object properties for the D2000 Thin Client.

The picture script can contain calls of RPC procedures on the assumption, that a reference variable is connected to the Picture displayer in the tab Script.
The syntax of such a call is e.g.:

CALL [_RefVarID] ProcName

From the picture script, you can change the picture linked to the displayer using the function %HI_SetConnectedObj. The function can be also used for objects linked to displayers of Report and Graph types.

Parameters

The tab in the upper part configures the binding of the selected external variable from the table of the attached schema.
