Beschreibung

draw_rectangle1_moddraw_rectangle1_modDrawRectangle1Moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1Mod liefert die Parameter für ein Rechteck parallel zu den Koordinatenachsen, das interaktiv durch den Benutzer im Fenster erzeugt worden ist.

Für die Erzeugung des Rechtecks werden die Parametern Row1InRow1InRow1InRow1InRow1Inrow1In, Column1InColumn1InColumn1InColumn1InColumn1Incolumn1In,Row2InRow2InRow2InRow2InRow2Inrow2In und Column2InColumn2InColumn2InColumn2InColumn2Incolumn2In erwartet. Nach einem Mausklick in die Mitte des erzeugten Rechtecks, kann dieses beliebig verschoben werden. Mit einem Klick in die Nähe einer Seite kann diese „angefasst“ werden, um die Ausdehnung des Rechtecks in senkrechter Richtung zu dieser Seite zu verändern. Klickt man auf eine Ecke des erzeugten Rechtecks, kann diese Ecke verschoben werden. Ein Klick mit der rechten Maustaste beendet die Prozedur. Unter macOS kann draw_rectangle1_moddraw_rectangle1_modDrawRectangle1Moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1Mod auch durch Drücken der Escape-Taste beendet werden.

Das Rechteck ist nach Beendigung der Prozedur nicht mehr auf dem Fenster sichtbar.

Ergebnis

draw_rectangle1_moddraw_rectangle1_modDrawRectangle1Moddraw_rectangle1_modDrawRectangle1ModDrawRectangle1Mod 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.
