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

Object

Connected object

Object of Picture type to display in the displayer. If Inherited instance is checked, the instance number of picture, opened in the displayer (subpicture), is the same as the instance of parent picture (picture that contain this displayer). If it is inactive, the instance number may be entered directly to 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 opening of the subpicture with the same instance number in several pictures.

Script

Reference variable

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 in the button. Multiple records are indicated by ",...".

Event

The listbox allows user to select a 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

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 D2000 Thin Client.

The picture script can contains calls of RPC procedures on the assumption, that a reference variable is connected to 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.

Note:
Subpicture keeps the properties of pictures, except for:

1. Subpicture may not contain a displayer of Report type.
2. To close a subpicture, there is not called the event OnClose. There is called only the event OnClose of the picture.
