For the sake of this question, let us suppose that I want a row of buttons. I want to put as many buttons in that row as I can fit on the screen, but no more. In other words, as long as a prospective button will not be cut off or have its text shortened, add it.
It seems that I should be able to do something like:
HorizontalFieldManager hfm = new HorizontalFieldManager();
int remainingWidth = Display.getWidth();
int i =0;
while(true) {
ButtonField bf = new ButtonField("B " + i);
remainingWidth -= bf.getWidth();
if(remainingWidth<0)
break;
hfm.add(bf);
i++;
}
add(hfm);
But this doesn't work. bf.getWidth() is always 0. I suspect that this is because the button has not yet been laid out when I query for the width.
So, perhaps I could just make sure the buttons are always the same size. But this won't work for a few reasons:
Different BB platforms have different looks for buttons and text that will fit on a button on a Curve won't fit on a button on a Storm.
3rd party themes may change the look of buttons, so I can't even count on buttons being a certain size on a certain platform.
Is there no way for me to actually check the remaining space before adding a button? It feels like a fairly useful feature; am I just missing something?
