Documentation YAML for OpenPetra Forms

Inheritance

• generally the yml files inherit from each other (BaseYaml)
  • this allows us to only define the default menu items once, in PetraForm.yaml, and they will be included in all derived forms

Attributes of the root node

• FormType:
  • abstract: if this is just used as a base form for other real forms
  • navigation: the main window, the module windows
  • edit: edit screens
  • crud: CRUD screens (Create, Read, Update, Delete)
  • find, browse: find screens
• MasterTable: if this is set, you will need to write less DataField attributes for the controls. The name of the controls will be matched to a field in the given table; if such a table field exists, it will be linked to the control.
• DetailTable: similar to MasterTable, but this is for the detail table; controls must have the word Detail after the prefix, eg. txtDetailAmount

Events

• Events: here you can link form events to methods in your code
  • eg. Activated: {class=System.EventHandler,method=FTheObject.TFrmPetra_Activated}

Actions

• Actions: actions can be used by menuitems, toolbarbuttons, and other controls; this is useful to be able to enable/disable an action on the whole screen, and to only define a certain action once, and refer to it from all controls that trigger the same action
  • eg. actClose: {Label=&Close, ActionId=eClose, Tooltip=Closes this window, Image=Close.ico}
  • eg. actMainMenu: {Label=Petra &Main Menu, ActionClick=FTheObject.OpenMainScreen}
  • Enabled: Actions can depend on other actions or conditions; they will be disabled if the condition is false; eg Enabled: cndSelectedSupplier; this can be set in a grid, with SelectedRowActivates; eg grdSupplierResult: {Dock=Fill, ActionDoubleClick=actSupplierTransactions, SelectedRowActivates=cndSelectedSupplier}

Controls

• Controls: see Screen scaffolding: controls

Menu & Toolbar

• Menu: TODO
• Toolbar: TODO

Layout

• Layout: TODO (Tabbed pages etc)

Another option for layout is the Controls property that can be used for Panels and GroupBoxes: You can use several rows to arrange the controls and they are aligned in a table layout.
