Drag & Drop Tree --> ALV

Beitrag von the-FoX (ForumUser / 87 / 0 / 0 ) »
Hallo,

ich habe mir einen Tree erstellt und ein ALV-GRID. Nun möchte ich ähnlich dem Programm: BCALV_GRID_DND_TREE etwas vom Tree in eine Spalte des ALV ziehen.
Ich habe die Events soweit registriert und ein Receiver-Objekt für den Tree und einen für das ALV angelegt.
Das für das ALV beinhaltet eine Methode für das Ereignis ONDROP.
Aber es wird nie in diese Methode gesprungen.
Die OnDRAG des Trees funktioniert jedoch einwandfrei.

Ich habe es so verstanden, dass erst die OnDrag Methode aufgerufen wird, dann die OnDrop und abschließend die OnDropComplete.
Gibt es da außnahmen ? Ist bestimmt nur ein kleiner Denkfehler von mir :(

Bräuchte mehr Infos.
Kann an Hand des Code-Ausschnittes keinen großen Fehler feststellen. Das Ereignis ondropcomplete gehört aber so weit ich weiß zum Tree (allgemein zum sendenden Control) und nicht zum Grid (s. BCALV_DND_01).
Wie sehen denn deine behaviour-Objekte aus? Und wie sieht die Methode für onDrag aus? Und welchen Knoten weist du den behaviour-Handle zu und wie? Wie sieht dein Datenobjekt für das DRAGnDROP aus ... :?:

Gruß, Heiko.

Der Fehler liegt darin, dass du auf jeden Fall ein Objekt definieren (und ggf. befüllen) musst, dass per Drag and Drop übertragen wird.

In der Methode 'handle_on_drag' des Trees musst du das Objekt (bei mir ein Objekt der Klasse lcl_dragdrop_data) befüllen (z. B. mit dem Text des entsprechenden Knotens) und die Referenzvariable (lx_dragdrop_object) dem EXPORTING-Parameter 'drag_drop_object' im Attribut 'object' mitgeben.

In der Methode 'handle_ondrop' nimmst du dieses Datenobjekt wieder in Empfang und weist es wieder einer Referenzvariablen zu (per widening cast (?=) weil unsere Klasse spezieller ist als die Klasse des Attributs 'e_dragdropobj->object'. Cast Error abfangen!).

Nun kannst du mit den Daten etwas anstellen. Dabei habe ich den relevanten Teil von display_flights auf die Sende- und Empfangsmethode verteilt. So wird also die komplette 1. Spalte des Grids mit dem Knotennamen gefüllt.

Vieleicht noch ein Nachtrag:

Wie kann i ch feststellen, auf welcher Spalte das Objekt gedropt wurde ?

Beitrag von popeiko (ForumUser / 47 / 0 / 1 ) »
Du hast bei der event_receiver Definition noch 2 andere Parameter (neben e_dragdropobj) definiert: e_row und e_column.

E_row liefert die Zeilen-ID deiner internen Gridtabelle und e_column den Namen der Grid-Spalte :wink:

Gruß, Heiko.

Genau @Heiko! Danke, hab ich auch gerade bemerkt ;)

Ich glaub ich hab da was übersehen *peinlich* der Drop Methode wird die Spalte ja bereits übergeben in E_COLUMN ;)
