Here is the situation:
I am trying to make an application in Racket that will be used with a touchscreen.
Naturally, I wanted to make lists, multi-selects, tabs, etc. a larger size, so that they can be more easily seen and clicked/tapped.
I wasn't sure how to do this, as there is no scaling/zoom arguments for list-boxes and tab-panels, at least none that I could see in the docs.
So figured using a larger font size = larger list-box rows & tab buttons.
It worked fine for a list-box%, but on a tab-panel, the font argument doesn't seem to do anything.
Below is some code that demonstrates the problem.
I am using Racket v8.7 & Windows 10.
#lang racket/gui
(define large-font (make-font
#:size 20
#:family 'default
))
(define main-frame (new frame% [label "Test"]
))
(define panel (new panel% [parent main-frame]
[min-height 150]
[min-width 200]
))
(define tab-panel (new tab-panel%
[parent panel]
[font large-font]
[choices (list "Tab 0"
"Tab 1"
"Tab 2")]))
(define label (new message%
[parent tab-panel]
[font large-font]
[label "Tab font should be like this"]))
(send main-frame show #t)
I create a larger font size and assign it to the tab-panel. But it doesn't seem to have any effect on the tab-panel%! Could someone please explain why this doesn't work, and how to get the effect I want?
