Summary

Functions

Set the x position of a texture within its OpenGL window

void lv_opengles_window_texture_set_x(lv_opengles_window_texture_t *texture, int32_t x)

Name	Type	Description
`texture`	`lv_opengles_window_texture_t *`	handle of an OpenGL window texture
`x`	`int32_t`	new x position of the texture

Set the y position of a texture within its OpenGL window

void lv_opengles_window_texture_set_y(lv_opengles_window_texture_t *texture, int32_t y)

Name	Type	Description
`texture`	`lv_opengles_window_texture_t *`	handle of an OpenGL window texture
`y`	`int32_t`	new y position of the texture

Set the opacity of a texture in an OpenGL window

void lv_opengles_window_texture_set_opa(lv_opengles_window_texture_t *texture, lv_opa_t opa)

Name	Type	Description
`texture`	`lv_opengles_window_texture_t *`	handle of an OpenGL window texture
`opa`	`lv_opa_t`	new opacity of the texture

lv_opengles_window_texture_t * lv_opengles_window_display_get_window_texture(lv_display_t *window_display)

Name	Type
`window_display`	`lv_display_t *`

Get the mouse indev associated with a texture in an OpenGL window, if it exists

lv_indev_t * lv_opengles_window_texture_get_mouse_indev(lv_opengles_window_texture_t *texture)

Name	Type	Description
`texture`	`lv_opengles_window_texture_t *`	handle of an OpenGL window texture

Returns: lv_indev_t * — the indev or NULL

there will only be an indev if the texture is based on an LVGL display texture and the window was created with use_mouse_indev as true

Delete an OpenGL window. If it is the last one, the process will exit

void lv_opengles_window_delete(lv_opengles_window_t *window)

Name	Type	Description
`window`	`lv_opengles_window_t *`	OpenGL window to delete May be `NULL`.

Add a texture to the OpenGL window. It can be an LVGL display texture, or any OpenGL texture

lv_opengles_window_texture_t * lv_opengles_window_add_texture(lv_opengles_window_t *window, unsigned int texture_id, int32_t w, int32_t h)

Name	Type	Description
`window`	`lv_opengles_window_t *`	OpenGL window
`texture_id`	`unsigned int`	OpenGL texture ID
`w`	`int32_t`	width in pixels of the texture
`h`	`int32_t`	height in pixels of the texture

Returns: lv_opengles_window_texture_t * — the new texture handle

lv_display_t * lv_opengles_window_display_create(lv_opengles_window_t *window, int32_t w, int32_t h)

void lv_opengles_window_texture_remove(lv_opengles_window_texture_t *texture)

Name	Type	Description
`texture`	`lv_opengles_window_texture_t *`	handle of an OpenGL window texture
