Buttons on cycle

Hello!
I parse "items" from DB (names, id, description, icon) from inventory. In inventory I write cycle which make buttons and then icons.
I want icons grid. I don't know how to write this.
In real:


All right:


P.S. Sorry for my bad English

 

Something like this will do the job.

Code (csharp):

1.  
2. int buttonWidth = 50;
3. int buttonHeight = 50;
4. int offset = 5;
5. for (int i = 0; i < rowCount; i++)
6. {
7.  for (int j = 0; j < columnCount; j++)
8.  {
9.   if (GUI.Button(new Rect(j * buttonWidth + offset, i * buttonHeight + offset, buttonWidth, buttonHeight), "Label"))
10.   {
11.    // Do something
12.   }
13.  }
14. }
15.  

Google nested loops and grids.

 

It work a bit wrong.
I parse items from BD, and show them in cycle via "foreach".
I use this.

Code (csharp):

1.  
2. for (int i = 0; i < 5; i++){
3.              for (int j = 0; j < 7; j++) {
4.                 foreach(string img in image){
5.                     if(img=="purseico")icon=purse_ico;
6.                     if(img=="noneico")icon=none_ico;
7.                     GUI.Button (new Rect(j * buttonWidth + offset, i * buttonHeight + offset, buttonWidth, buttonHeight), icon);
8.                 }
9.             }
10.         }
11.  

Buttons are really located grid. But showed 7 buttons instead 1 button in one slot, since their DB 7.

I corrected this problem

Code (csharp):

1.  
2. foreach(string img in image){
3.             if(img=="purseico")icon=purse_ico;
4.             if(img=="noneico")icon=none_ico;
5.             if(j<7){
6.                     j++;
7.                     if(j==7&i<5){
8.                         j = 0;
9.                         i++;
10.                     }
11.             }
12.             GUI.Button (new Rect(j * buttonWidth + offset, i * buttonHeight + offset, buttonWidth, buttonHeight), icon);
13.         }
14.  

Thank you!
