java - JButton and its Location methods acting very weird -


my problem is, when create jbutton, whithin constructor, set location relative coordinates, x = 5, , y = 6, using following code:

this.setlocation(new point(x, y));

but after trying location using getlocation() method, returns 0,0. please note happens every jbutton trying place on grid layout powered jframe, , during debugging process, have noted location being instantiated.

can explain me why happens, , if can fix somehow?

edit:

the constructor (the brick class made, extends jbutton):

public brick(int posx, int posy) {         this.setlocation(new point(posx, posy));         this.setvisible(true);     }

i make 100+ of them in 2 loops:

   (int row = 0; row < 15; row++) {     (int column = 0; column < 15; column++) {     brick brickie = new brick(row, column);     }    }

but afterwards, if wanna pick brick , check location this:

point bricklocation = brickie.getlocation();

both bricklocation.x == 0 , bricklocation.y == 0

you trying change button location when automatically assigned layout manager (your gridlayout). why getting same value - layout overwrites it.

to able change component bounds/location (including buttons) manually - have set "null" container's layout. after change location/size/bounds , affect components positions.

also don't need use "setvisible(true)" - default flag true components (even aren't displayed yet).
