is is possible to scale a lwtk application?

[mark-summerfield]

I'm trying out some of the examples using lua 5.4.

1. How can I set the font size for each type of widget?
2. How can I scale the whole application? For example, on my laptop the screenshot actually looks much smaller than github shows.

You can scale the whole lwtk application by setting the scaleFactor style parameter. This can be done by setting this style parameter somewhere in the style hierarchy. This can be done for the whole application for example in example01.lua replace

local app = Application("example01.lua")

with

local app = Application("example01.lua", { scaleFactor = 3 })

or you can set this style parameter for an individual widget subtree, see the documentation for lwtk.Style.

Anyway, there should be some support for hardware dependent screen scale factor, so my question is:

What does

print(app:getScreenScale())

give on your platform?

However, if you only want to increase the font size and not the whole scale factor and not providing a totally new style there is up to now no easy solution. I will try to provide a patch for this for a better solution.

Update: with commit 429cfe9 you could replace

local app = Application("example01.lua")

with

local app = Application("example01.lua", { TextSize = 20})

for overriding the TextSize style parameter for all widgets.
