I want to display in an output field a number, who can change between say 0 an 100 during the simulation. The output should be in the form 24.568. How should the format entry look? If I leave it blank, the display, after the simulation is paused, is 4.856. When I resize the Window, then the display shows 24.856. The same when I use format 0.000.
The format you want can be either 0.000 (the default) or 0.### The difference is that 0.000 will display 24.4 as such 24.400, while 0.### would do it as 24.4.
The problem you report is not with the format, but with the SIZE of the field. I suggest that you set the "Columns" property of the field to something like 6 or 7. This is not exactly the number of digits to show, but close to it (actually a bit larger - that's something Java decides, not me). Or you can also set the property size of the field to something appropriated. Though the columns property is better because it is more reliable in case of change of fonts.
