multiple gui

[samanyu]

Hi all,
I know this may have been asked a zillion times, but I couldn't find any direct replies in my search.
My question is, suppose i use a main GUI(GUI1) button to open another GUI, say GUI2, how do I close GUI2 without closing GUI1?

Restated, I only want one GUI window to close, the remaining to stay open. That includes if i want to close GUI3 and not GUI2, even if i used GUI2 to call GUI3.
Closing GUI1 should be definitive, ofcourse.

Please help.
Thanks.

Have you tried using the setVisible method?

[samanyu]

i think i found a cross post. i'll close this thread and come back later if necessary.
i haven't. i will though, thanks.

[samanyu]

actually, help me out, if i use the close button, how do i call setVisible? what is the mouse event code?

[Norm]

how do i call setVisible?

Have you looked up that method in the API documentation? That should explain how to use it.

what is the mouse event code?

How is this related to closing a window?

[samanyu]

what is the mouse event code?

i don't know. the code in the constructor for the main class is exit_on_close. its generated by a click on the x box on the JFrame. so i figured i might need an event trigger for the set Visible.
i have a lot to learn!! :)

[samanyu]

this is the code i use now. "setDefaultCloseOperation(EXIT_ON_CLOSE);"
what do i change it with?

Time to read the API doc for the method you are using to see what options it has.

[samanyu]

got it. thanks for not giving me the easy way out. :D

also could you suggest a method for converting a regular rectangular grid of (i,j) to a hex grid of (i,j)?

method for converting a regular rectangular grid of (i,j) to a hex grid of (i,j)

Please define in java code a regular grid and a hex grid. I have no idea what you mean by those terms.

[samanyu]

this is the code i have use.
public void paintComponent( Graphics g ){ // main rendering recipe
Graphics2D g3 = (Graphics2D)g;
g3.setColor( Color.black );
g3.fillRect( 0, 0, getWidth()-1, getHeight()-1 );
int w = 810 / (810/30);
int h = 630 / (630/30);
for(int col=0;col<(810/30);col++){
for(int row=0;row<(630/30);row++){
for(int k=0; k<works1.l; k++){
if( jiffy.rulbas[col][row] == k){
g3.setColor(jiffy.colors[k]);
repaint();

} g3.fillRect( col * w +1, row * h +1, w-2, h-2 );

} }}
it creates a rectangular grid on a display window.
i need to create a hexgrid. and i am having difficulty visualising the pixels, and also drawing the hexagon itself.

[Norm]

What is a hex grid? Do you have an algorithm or design for drawing one? Not really part of java coding.

To compile and execute this code, you need a definition for jiffy

[samanyu]

the code is executing. a hex grid, is one like in this picture: Google Image Result for http://www.thealmightyguru.com/Humor/Inventions/Images/Grid-Hex.gif

i do have an algorithm, but it might take time to dig it up. i will post it tomorrow, its past 12 here in japan.
thanks for your help.

gamedev.net used to have some articles on drawing hex maps, and using masks to figure out which hex a user has clicked on.
I would suggest using an image file for the hexes. It's a lot easier.

I just had a post like this; I wanted to have a JFrame (in swing) and multiple JPanels. Just remove the current JPanel when a button is clicked and add another one.

to get rid of the GUIs JFrame just use the method: frame.dispose();
