Namespace Tripous.Desktop

Classes

AppForm

A base class for a UI embeddable in Avalonia.Controls.TabItem controls.

AppFormDialog

Shows a modal window with an embedded form (UserControl)

AppFormPagerHandler

Handles a tab control which displays forms (UserControls) embedded in TabItems.

AvaloniaAssets

Handles Avalonia resources.

CommandTreeViewForm

Displays application commands in a tree view.

ConfigDialog

Displays and edits registered application configuration properties.

ControlBinding

Binding information for simple controls (single-line controls, lookup combo-boxes and locator boxes).

ControlBindingHelper

Provides helper methods for binding Avalonia controls to data rows.

DataForm

A data form with a List part and an Item part.

All user initiated form actions should enter through Execute(DataFormAction). The ExecuteXXXX() methods are the action handlers and they are the only methods that should directly change, or eventually cause a change to, the FormState.

Low level data operation methods, such as ListSelect(), Insert(), Load(object), Delete(object) and Save(), should be called only by the corresponding ExecuteXXXX() method. This keeps UI commands, keyboard shortcuts and toolbar buttons on the same execution path.

The cancel flow is intentionally split. ExecuteCancel() handles the Cancel action. ExecuteCancelEdit() handles only rejecting item changes. When an item has changes, Cancel asks for confirmation, rejects the changes, refreshes the item controls and stays in the Item part. A second Cancel, with no changes left, returns to the List part.

Startup is the only intentional exception to the general rule. ExecuteStartAction() may call ExecuteEdit(RowId) or ExecuteInsert() directly and delayed through the UI dispatcher. At startup the list part may not be loaded yet, so Execute(Edit) cannot always resolve the desired row through the current list row. This exception is for bootstrapping only; normal UI actions should still use Execute(DataFormAction).
