Hi Guys,

How could you set the width of the DropDown window (which displays all choice items of your choice field)? The application automatically sets the width based on the width of the choice items.

Thank you

no way to modify it. if you need it different create your own objectchoicefield, for example leveraging objectlistfield and popupscreen.

Thank for your confirmation, you saved my time.

But that is a bad news. It  must be too much work to create own objectchoicefield.

Never had the need to use this, so haven't tried it, but I note the ObjectChoiceField includes a method called:

getWidthOfChoice();

Now I presume that the Width is in pixels, and that the normal process would invoke using the field.font and doing a getAdvance().  But I've often wondered if by changing this I would change the actual width of the Field.

Possibly worth a try.  If you do try it, let us know.

Hey Peter,

getWidthOfChoice() works!

Because it is getting width of only one choice item, I thought it is not for field width and I completely ignored it and spent hours for work around.

And just to mention, buy using this, it does not affect the actual width of the Field.

Thanks

Oops! here is correction

getWidthOfChoice() works fine with Version 4.6 but it is not working on Device software Version 5.0

What a nightmare.....

You want to make the "button" wider? I find a solution: add spaces to the text you want to show, so it's wider!

May be a better way:

override layout(int width, int height):

protected void layout(int width, int height) {

	setMinimalWidth(width - 61); // 61 is the min value, lower than 61 will not work
	super.layout(width, height);
	
}
