What colour was the old switch/slider “on”?

Thanks!

You can use any image editor software to pick the color. E.g. Paint or GIMP. But there are online tools too, such as Online Image color picker

I was hoping you could tell me what the exact colour was.

Thanks

From the lv_conf_template.h of v7:

Thanks for that.

I have managed to get the sliders to have the right background colour for the LV_PART_INDICATOR but for the life of me I cant get the switch to do the same.

	lv_obj_t * switchName = lv_switch_create(parent);
    lv_obj_set_pos(switchName, xpos-20, yPos-10);
	lv_obj_set_height(switchName, 35);                          /*Set height*/
	lv_obj_set_width(switchName, 100);
    //lv_obj_set_style_bg_color(switchName, lv_color_hex(0x494f57), LV_PART_INDICATOR);
    lv_obj_set_style_bg_color(switchName, lv_color_hex(0x01a2b1), LV_PART_INDICATOR);

Any ideas what II am doing wrong?

Thanks

For the switch, you should use LV_PART_MAIN.

elgerg · February 12, 2022, 11:14am

MAIN if for the off state:

I want to adjust the on state:

embeddedt · February 12, 2022, 1:28pm

I believe you just need LV_PART_MAIN | LV_STATE_CHECKED as the selector. I’m not at a PC to confirm the name right now, so hopefully my memory is accurate.

elgerg · February 12, 2022, 1:35pm

LV_PART_MAIN | LV_STATE_CHECKED doesn’t make any difference either.

According to the docs switch only has 3 parts:

It looks like main is off, knob is the round part and I assumed like slider indicator was for the “on” part but it seems to do nothing.

Maybe I found a bug?

Thanks

It looks like LV_PART_INDICATOR | LV_STATE_CHECKED works for me.

elgerg · February 13, 2022, 12:48pm

Bingo, that works as expected.

Thank you!!
