Little problem with Open File dialog
This is the code im using, i would like you to test it. A very small "frame" opens in the top left corner in the screen.
public class OpenFile extends Frame {
Frame container = new Frame();
String path = "";
public OpenFile() {
FileDialog dialogFile = new FileDialog (container, "Choose file", FileDialog.LOAD);
dialogFile.setVisible (true);
String name = dialogFile.getFile();
String directory=dialogoArchivo.g
if (name != null);
{
path = directory + name;
System.out.println(path);
this.addWindowListener (new WindowAdapter () {
public void windowClosing(WindowEvent e) {
hide();
}
});
}
hide();
}
}
I dont know why a little frame appears in the corner of the screen. What king of changes do i have to make to solve this problem???

>>Frame container = new Frame();
The above is redundant (you're already extending Frame) and will cause problems
So
>>FileDialog dialogFile = new FileDialog (container, "Choose file", FileDialog.LOAD);
should be
FileDialog dialogFile = new FileDialog (this, "Choose file", FileDialog.LOAD);
You will of course need to set a size for OpenFile before you show it.

Thank you for your help CEHJ....I solved the redundancy problem...but im still having problems. A frame appears in the top left corner of the screen...
How are you using your OpenFile class? By the way, you'd be better to have a showDialog method or something, rather than trying to show the dialog in the constructor

Im calling the OpenFile this way: (of course this is in other class)
OpenFile select = new OpenFile();
select.show();
if( (select.path).equals("null
//No action
}
else{
..........................
}
Do you tell me to use select.showDialog instead of select.show()...????
How can i make a showDialog method???
OpenFile select = new OpenFile();
select.show();
if( (select.path).equals("null
//No action
}
else{
..........................
}

Hey CEHJ...the problem is solved now!
The problem was the line "select.show();"
why?
Because the Open file dialog opens by itself by only making the contructor of the class OpenFile. That line shows another frame.
Well, thank you so much, you have given me a clearer situation of my problem...
