Beschreibung

draw_line_moddraw_line_modDrawLineModdraw_line_modDrawLineModDrawLineMod liefert die Parameter für eine Gerade, die interaktiv durch den Benutzer im Fenster erzeugt worden ist.

Für die Erzeugung der Gerade werden die Koordinaten Row1InRow1InRow1InRow1InRow1Inrow1In, Column1InColumn1InColumn1InColumn1InColumn1Incolumn1In des Startpunktes und Row2InRow2InRow2InRow2InRow2Inrow2In,Column2InColumn2InColumn2InColumn2InColumn2Incolumn2In des Endpunktes erwartet. Klickt man auf einen Endpunkt der erzeugten Gerade, kann diesen Punkt verschoben werden. Nach einem erneuten Mausklick in die Mitte der erzeugten Gerade, kann diese beliebig verschoben werden. Ein Klick mit der rechten Maustaste beendet die Prozedur. Unter macOS kann draw_line_moddraw_line_modDrawLineModdraw_line_modDrawLineModDrawLineMod auch durch Drücken der Escape-Taste beendet werden.

Die Gerade ist nach Beendigung der Prozedur nicht mehr auf dem Fenster sichtbar.

Ergebnis

draw_line_moddraw_line_modDrawLineModdraw_line_modDrawLineModDrawLineMod liefert den Wert 2 (H_MSG_TRUE), falls das Fenster gültig und der benötigte Zeichenmodus (siehe set_insertset_insertSetInsertset_insertSetInsertSetInsert) verfügbar ist. Ansonsten wird eine Fehlerbehandlung durchgeführt.
