Description
What MCU/Processor/Board and compiler are you using?
Simulator
What LVGL version are you using?
V7.1.0
What do you want to achieve?
To let me get into LV_EVENT_DRAG_BEGIN and LV_EVENT_DRAG_END event
What have you tried so far?
I’ve tried ‘lv_obj_set_drag()’ and ‘lv_obj_set_drag_dir()’,worked,but I only want to redirect to another page when I swipe screen from left to right.
‘lv_obj_set_drag()’ doesn’t reach my expectation.Just like ‘lv_obj_set_drag_dir(obj, LV_DRAG_DIR_HOR)’, but only from left to right.
Code to reproduce
Add a code snippet which can run in the simulator. It should contain only the relevant code that compiles without errors when separated from your main code base.
The code block(s) should be formatted like:
/*You code here*/
#include "test.h"
#include "../../lv_examples.h"
static lv_obj_t* screen;
void event_handler(lv_obj_t* obj, lv_event_t event);
void test_start(void)
{
screen = lv_scr_act();
lv_obj_t* container = lv_cont_create(screen, NULL);
lv_obj_set_size(container, 256, 402);
lv_obj_align(container, screen, LV_ALIGN_CENTER, 0, 0);
lv_obj_set_event_cb(container, event_handler);
}
void event_handler(lv_obj_t* obj, lv_event_t event)
{
//printf("event:%d\n", event);
if (event == LV_EVENT_DRAG_BEGIN)
{
lv_indev_t* indev = lv_indev_get_act();
if (indev != NULL)
{
if (indev->proc.types.pointer.drag_dir == LV_DRAG_DIR_HOR)
{
if (indev->proc.types.pointer.vect.x > 0)
printf("left to right\n");
else if (indev->proc.types.pointer.vect.x < 0)
printf("right to left\n");
}
}
}
}
Screenshot and/or video
If possible, add screenshots and/or videos about the current state.
