Java Swing UI Ausrichtungsproblem

Question

Ich habe eine Anforderung, nach der die UI wie unten abgebildet angezeigt werden sollte.

Ich habe versucht, das gleiche zu erreichen, indem Sie das unten Stück Code.

Die Komponenten werden jedoch wie in der Abbildung unten angezeigt. Bitte helfen Sie, wie Sie diese beheben können.

Answer 1

Hinweis: Bitte versuchen Sie, Ihre Code-Snippets zu verkleinern, damit sie für andere leichter lesbar sind.

Wenn Sie GridBagLayout verwenden, müssen Sie in der Regel Felder mit einem Gewicht von 1 verwenden, um die Leerstellen auszufüllen. Stellen Sie zunächst gbc.fill = GridBagConstraints.BOTH; ein.

Fügen Sie dann leere Felder hinzu und verwenden Sie Gewichte, um den Platz auszufüllen, wie in der Abbildung unten zu sehen ist. Die Tafeln oben und unten sollen den ganzen Platz einnehmen, den sie bekommen, also weighty = 1; und überspannen auch zwei Spalten, also gridwidth = 2. Die Paneele in der Mitte nehmen die verbleibende Höhe ein. Das Panel auf der rechten Seite sollte dann die verbleibende Breite einnehmen, also weightx = 1. So nimmt Ihr Panel immer nur den verbleibenden Platz ein.

Answer 2

Sie könnten versuchen, ein Box.createHorizontalGlue() hinzufügen, am äußersten linken Teil, aber Sie müssen sicherstellen, dass es den größten gridbagconstraints.weightx;

Zum Beispiel hat:

gbc.weightx = 1;//needs to be more than 0 so it works. 
gbc.gridx = 4;//needs to be the largest gridx in the panel + 1 
jpPanel3.add(Box.createHorizontalGlue(), gbc2);
