incorrect bindings

[dsl400]

I trying to compile micropython with lvgl 9.2.1 to use the code generated by Gui Guider for the micropython simulator on my esp32 device

So far everything looks fine, for the basic examples. The script exported by Gui-Guider requires some small adjustments mostly for paths

When trying a more complex example I encountered this error

AttributeError: 'lv_span_t' object has no attribute 'style'

To add a little more context ...

mode = lv.obj()
mode_tileview = lv.tileview(mode)
mode_tileview_mode_a = mode_tileview.add_tile(0, 0, lv.DIR.RIGHT)
mode_spangroup_1 = lv.spangroup(mode_tileview_mode_a)
mode_spangroup_1_span = mode_spangroup_1.new_span()
mode_spangroup_1_span.style.set_text_color(lv.color_hex(0xffffff)) <<< attribute style is not accessible 

One solution would be to patch the code and replace .style. with .get_style(). however I am looking for a solution that does not require modifications on the exported code

Any suggestion would be highly appreciated!!

the fields of lv_span_t are not exposed to MicroPython because that structure is private.

so what you need to do is the following..

mode = lv.obj()
mode_tileview = lv.tileview(mode)
mode_tileview_mode_a = mode_tileview.add_tile(0, 0, lv.DIR.RIGHT)
mode_spangroup_1 = lv.spangroup(mode_tileview_mode_a)
mode_spangroup_1_span = mode_spangroup_1.add_span()
style = mode_spangroup_1_span.get_style()
style.set_text_color(lv.color_hex(0xffffff))
mode_spangroup_1.set_span_style(mode_spangroup_1_span , style)

the generated code works in micropython inside Gui-Guider simulator
I am trying to understand how replicate that behavior on my device

the generated code in GUI Guider might not be for the version of LVGL that this binding is using. I am not sure when the structure was moved into the private scope but I can tell you that it was moved.
