Über

MultiDoc ist ein Lazarus Package zum Ersetzen des Standard MDI Interface.

This component permit to write pseudo-MDI application with Lazarus. It is not a real implementation of the MDI interface but it give to your application the capability to use many resizable sub-form.

Es gibt 2 Komponenten:

• TMultiDoc : the main form docking area.
• TChildDoc : the child container with resizeable border and button.

I do them with a graphical software in mind but they are probably useful for a range of applications.

Anmerkungen

You are not limited to show the docking area in the full main form. You can place the TMultiDoc anywhere you want or use multiple one! A combination with a TNotebook may give something similar to a multi-desktop.

Installation

• Kompilieren und installieren sie multidocpackage.lpk
• Öffnen sie das Beispiel demo/demomultidoc.lpi

This example can be used as a skeleton for a new application.

Verwendung

Zur Entwicklungszeit:

• On the application main form place a TMultiDoc.
• Create a child form with a main TPanel.
• Put all the object you want for the child to the panel, write the event, etc...
• Do not rely on some TForm event as this form is never show.

Zur Laufzeit:

• Create a new child from TMultiDoc.NewChild
• Create a child form with the new childdoc as owner.
• Assign the main panel to the Dockedpanel property.

Convert a Delphi MDI application

Converting a MDI application is simplified by the availability of the same component for Delphi and Kylix.

Convert first your application to MultiDoc in Delphi,then convert to Lazarus. This require some work but among the advantage you avoid the ugly XP border around your child forms.

Replace the standard MDI function as below:

  MDIChildCount   -> MultiDoc1.ChildCount
  ActiveMdiChild  -> MultiDoc1.ActiveObject
                  or MultiDoc1.ActiveChild
  MDIChildren[i]  -> MultiDoc1.Childs[i].DockedObject
                  or MultiDoc1.Childs[i]

Die Delphi Komponente ist im Package enthalten. Entpacken sie multidoc-delphi.zip und installieren MultiDocD6.dpk oder MultiDocK3.dpk.
