| == Visual Modelling of multiple visual objects ==
| |
| The VDF studio is geared towards handling source code with one main panel or dialog, and accordingly when the programmer switches to a visual represntation the Studio will display the first such object in the source file.
| |
| However in some cases the programmer may find it useful to be able to include such items as password or other popup dialogs in the same source file as the main object.
| |
| To allow the main object to be modelled and hide the 'lesser' objects, it is necessary to change the class of the popup objects to be non-modellable.
| |
| | |
| I do it this way.
| |
| | |
| <source lang="vdf">
| |
| //Object Freddialog is a cmydbmodalpanelnomodel //uncomment to hide from modelling
| |
| Object Freddialog is a cmybmodalpanel //comment this line to hide from modelling
| |
| ...
| |
| End_object
| |
| </source>
| |
| | |
| and here's the class, the only important line being the { DesignerClass=None } at the top
| |
| | |
| <source lang="vdf">
| |
| ''
| |
| //***************************************************************************
| |
| //*
| |
| //* Class: cMyDbModalPanelnomodel
| |
| //* Package Name: cMyDbModalPanelnomodel.pkg
| |
| //* Use for password popups etc. This stops a popup being modelled in the Studio
| |
| // as otherwise the main panel isn't getting seen. Mostly used in Menus
| |
| //*
| |
| //***************************************************************************
| |
| Use dfdbmdpn.pkg
| |
| { DesignerClass=None } //Daves mod to stop this sneaking in and being modelled when the meaty stuff is MUCH lower
| |
| Class cMyDbModalPanelnoModel is a dbModalPanel
| |
| Procedure Construct_object
| |
| Forward Send Construct_Object
| |
| End_Procedure
| |
| End_Class // cMyDbModalPanel
| |
| ''
| |
| </source>
