In this package we provide an example of a model type GraphRep which contains a Button that triggers some event. In our case it is a print-button which opens a print dialogue when ckicking on it:




Downloads

The files below contain an example library (Print Button.abl) and an example model (Print Button demo model.adl). A step-by-step configuration guide is presented in the Hands-On section below. It completely describes how to build this example library.

Print Button.abl
Print Button demo model.adl


Hands-On

1) Create new class __ModelTypeMetaData__



Steps to create class __ModelTypeMetaData__

• Go to the Library management, select a dynamic library and click Class hierarchy.
• Click View and select Metamodel.
• Select __D-construct__ (Metamodel)
• Click New --> New class; name it __ModelTypeMetaData__  (two underscore signs!).

2) Add new attribute to class __ModelTypeMetaData__



Steps to add attributes to class __ModelTypeMetaData__:

• Select class __ModelTypeMetaData__
• Click New --> New attribute...
• Name new attributes and select type according figure above: (1) name: Print Button GraphRep, type: Longstring.

3) Configure Print Button GraphRep attribute

• Double click Print Button GraphRep attribute, set Standard value to:

• Make sure that the file btn_print.png is contained in the database (close the Library management and go to Extras --> File management…).

4) Creating _PrintModel_ attribute (Programcall)

• Select class __ModelTypeMetaData__
• Click New --> New attribute...
• Name new attributes and select type according figure above: (1) name: _PrintModel_, type: Programcall.

5) Configure _PrintModel_ attribute (Programcall)

• Double click _PrintModel_ attribute
• Set Standard value to: Print Model
• •Click Facets and set EnumerationDomain to:

• Make sure that the file PrintModel.asc is contained in the database.

6) Define Model type

• Go back to the Library management and select your current Dynamic Library.
• Click Library attributes… -->  Add-ons and define the following model type according the figure above:

Result

In order to see the result, open Print Button demo model.adl in the ADOxx Modeling Toolkit.

• Clicking the Print Model button triggers (via HOTSPOT command) the Programcall _PrintModel_, which executes the file PrintModel.asc.
• Note, that the print icon (btn_print.png) is represented on the drawing area only.

Dear Benedikt,
A model type can have only one graphical representation. To display two buttons in a model type you must do this via the GraphRep attribute. The GraphRep code for two different buttons in a model type could look like this:

GRAPHREP layer:-3

IF (_outdevtype = "drawingarea") {
SET printIcon:"db:\\btn_print.png"
BITMAPINFO (printIcon)
BITMAP (printIcon) x:1cm y:0.5cm w:1.5cm h:1.5cm
HOTSPOT "_PrintModel_" text:"Print Model" x:1cm y:0.5cm w:1.5cm h:1.5cm
SET printIcon2:"db:\\btn_print.png"
BITMAPINFO (printIcon2)
BITMAP (printIcon2) x:3cm y:0.5cm w:1.5cm h:1.5cm
HOTSPOT "_PrintModel_" text:"Print Model" x:3cm y:0.5cm w:1.5cm h:1.5cm
}
