mein keyListener scheint Konflict haben mit mouseListener

[kai]

Unten ist mein Programm,
Ich will in meinem Programm so etwas realisieren, nähmlich nachdem ich textButton gedruckt und mouse auf PaintPanel gepressed und ein Text, die per Tastertur eingegeben wird, angezeigt wird, und zwar, beim Eingeben gleichzeitig erscheinen.
Jetzt das Problem ist wenn ich zuerst mouse irgendwo gedruckt dann das keyListener macht keine Arbeit mehr. Aber warum, verstehe ich das nicht. Darf keyListener, mouseListener eigentlich nicht gleichtzeitig benutzt werden? Ich finde nicht, aber aus welcher Grund kommt mein Problem? Kann jemand hier mir helfen?

[Beni]

Ich hab im MouseListener noch ein

((Component)event.getSource()).requestFocus();

eingefügt. Dann wird zumindest etwas abgefangen.

 

[kai]

Danke, ich probiere mal.

Beni,
wo soll dieses Code eingesetzt werden? Kannst Du mir ein paar Code im Zusammenhang geben? Oder schicke mir das von Dir verbesserte Progamm per email schicken? mein Emailaddresse : kaihua1@yahoo.com

 

[Beni]

Sorry, ich sollte ein bisschen ausführlicher schreiben :roll:

 private class MouseHandler extends MouseAdapter
  {
    final int LMOUSE = 1;
    final int RMOUSE = 3;
    int mouseTyp;
    public void mousePressed(MouseEvent event)
    {
    	((Component)event.getSource()).requestFocus();
    	
      int tempX, tempY;
      ProgrammZustand temp;

Das hilft dir hoffentlich mehr.

 

[kai]

Beni,
Du bist sehr nett, ich danke Dir very much.
kai

Beni,
gucke mal hier, :lol: :lol:

public void mousePressed(MouseEvent event)
{
((Component)(event.getSource())).requestFocus();
((Component)(event.getSource())).addKeyListener(new MyKeyListener()); // ich habe es hingefügt.
int tempX, tempY;
ProgrammZustand temp;


hahahahahahahaha, es scheint jetzt schon etwas.
