Image button (lv_imgbtn)

Overview

The Image button is very similar to the simple 'Button' object. The only difference is that it displays user-defined images in each state instead of drawing a rectangle.

You can set a left, right and center image, and the center image will be repeated to match the width of the object.

Parts and Styles

LV_PART_MAIN Refers to the image(s). If background style properties are used, a rectangle will be drawn behind the image button.

Usage

Image sources

To set the image in a state, use the lv_imgbtn_set_src(imgbtn, LV_IMGBTN_STATE_..., src_left, src_center, src_right).

The image sources work the same as described in the Image object except that "Symbols" are not supported by the Image button. Any of the sources can NULL.

The possible states are:

LV_IMGBTN_STATE_RELEASED
LV_IMGBTN_STATE_PRESSED
LV_IMGBTN_STATE_DISABLED
LV_IMGBTN_STATE_CHECKED_RELEASED
LV_IMGBTN_STATE_CHECKED_PRESSED
LV_IMGBTN_STATE_CHECKED_DISABLED

If you set sources only in LV_IMGBTN_STATE_RELEASED, these sources will be used in other states too. If you set e.g. LV_IMGBTN_STATE_PRESSED they will be used in pressed state instead of the released images.

States

Instead of the regular lv_obj_add/clear_state() functions the lv_imgbtn_set_state(imgbtn, LV_IMGBTN_STATE_...) functions should be used to manually set a state.

Events

LV_EVENT_VALUE_CHANGED Sent when the button is toggled.

Learn more about Events.

Keys

LV_KEY_RIGHT/UP Go to toggled state if LV_OBJ_FLAG_CHECKABLE is enabled.
LV_KEY_LEFT/DOWN Go to non-toggled state if LV_OBJ_FLAG_CHECKABLE is enabled.
LV_KEY_ENTER Clicks the button
