Thread: javadisplay images

From post#92, re-ordered:

1)image created
2) new image added to a panel
3) button added to panel
4)panel with the image and the button added to the panel with the gridlayout
5)filled panel added to the frame
6)GUI packed and shown

It looks like steps 5 and 6 (from post#106) are not done last. They are done before steps 2, 3 & 4

For learning how to create a GUI make a test program as done in post #51. When that works, change it by using post#70.

The order of the steps is important.


Try the steps in the order I recommended and see what happens then.

ive ammended it so its it is in right order now jsut not printing out the the way i want it to, there i somthing im doing wrong but i dont knw what.

Now what about step 4?

is this in the wrong place?

That has nothing to do with creating the GUI.

4)panel with the image and the button added to the panel with the gridlayout

No. That code does the opposite: adds gridpanel to the cellpanel (which should contain the image and button) Look at post#70

i have added it there because if i put these anywhere else they give me errors.

when i put this at the top i get errors espeically that "icon" so im not sure on what to do here.

4)panel with the image and the button added to the panel with the gridlayout

That says to create a panel, add the two things to it and add that panel to the gridpanel. See post#70

That's it for me tonight. I'll be back tomorrow.

after all this and the stress i dont think i need it need. im making a learing application.. how will my users learn from this memory is what my tutor asked me?

I'm not sure I understand what you are asking. Is it a question about the code or what?

Honestly I also did not understand this english phrase .....

Please help me with some easy ideas, as i do not have much time.

stresstedout, listen please. This thread has arrived at post #123 (with my current answer) and we have spoken about a lot of things. Still now I don't know if you have well understood the concepts and examples I have posted. And you not even have answered positively or negatively about this ..... I suppose of no .....
And now you say, if I understand correctly, that you don't know what you want to/can do??

I wasted my time in trying to repeat things many times and posting different examples and I was a bit frustrated by this. Sorry but this is not a good incentive (at least for me) to continue on this thread/topic and I also think this is not the right way to use the forum .....

Andbin, I thought of making a memory and thats what i have been doing with help of youself and norm, i am really appreciate that you took time out to help me. I have un

So you want an idea for a game? There are lot of games that are made with a "grid" of images: Tic-tac-toe, Chess, Reversi, Peg solitaire, Sudoku, Scrabble. Just to name a few.

In these games the difficulty, at programming level, is not the display of images! The real difficulty is about all the "logic" that is behind the game. This logic can be very complex, you need not just some tens of lines of code but hundreds of lines.
And if for a game you want to develop some sort of "artificial intelligence" for a computer player, the complexity raises by 40, 50 times so that you need thousands and thousands of lines of code.
And If you don't write this code using all the good OOP principles, design patterns, valid data structures, etc.. you will end up to a code that is only absurd, incomprehensible, clunky and so on ...

I can understand .... and remember (for the future), that I like to help but I like people who have good will and want to read, study, try and experiment in order to understand.
