Description
About a day ago I posted a similar problem with deletion of characters, where there were some inexplicable behavior when I tried to delete an object - in this case a window.
I have a button in the high right corner that I use to delete the current window, but over last few days I have been getting some weird crashes. The weirdest part is that the crash is not at all consistent, but rather random, and I can’t find anything in my code that would cause such behavior - keep in mind that i’m not at all experienced.
Note - this code has worked previously in v6
What MCU/Processor/Board and compiler are you using?
As the video/gif shows I currently run the simulator.
What do you want to achieve?
I would just like to know if the crashes is just caused by some of my faulty code, and then what i’m doing wrong.
What have you tried so far?
I have tried to switch some things around that may have caused it, but it haven’t helped. As an example i tried to switch out the parent: lv_scr_act() //trying to get the current screen, could be the problem with something i’m more certain will work.
I have also tried to find some kind of pattern, like pressing on the edge of the button or something the like, that could be the problem, but again i haven’t had any luck.
Couldn’t find anything about changes to deletion of objects in the documentation.
Code to reproduce
This should be the relevant code, I think
The window shown in the video, with the buttons code included
(there is also other code in the window, but I hope this is all thats needed):
/*Create a window*/
winPin = lv_win_create(lv_scr_act(), NULL);
lv_win_set_header_height (winPin, 0);
lv_win_set_title (winPin, "Add/remove user"); /*Set the title*/
lv_win_set_btn_width (winPin, 0);
lv_obj_add_style (winPin, LV_WIN_PART_BG, &style_win_bg);
lv_obj_add_style (winPin, LV_WIN_PART_HEADER, &style_win_header);
//Add control button to the header
lv_obj_t *close_btnPin = lv_imgbtn_create(winPin, NULL); /*Add close button and use built-in close action*/
lv_obj_set_event_cb (close_btnPin, close_window);
lv_obj_add_style (close_btnPin, LV_BTN_PART_MAIN, &style_symbol);
lv_imgbtn_set_src (close_btnPin, LV_BTN_STATE_RELEASED, &LV_SYMBOL_CLOSE);
lv_imgbtn_set_src (close_btnPin, LV_BTN_STATE_PRESSED, &LV_SYMBOL_CLOSE);
lv_obj_set_pos (close_btnPin, 210, 15);
lv_obj_set_size (close_btnPin, 20, 20);
lv_obj_set_ext_click_area (close_btnPin, 3, 3, 3, 3);
The handler for clicks on the button:
void close_window(lv_obj_t* obj, lv_event_t event) {
if (event == LV_EVENT_RELEASED) {
if (obj != NULL) {
if (obj == close_btnBat) {
lv_obj_del(winBat);
}
if (obj == CloseBtnPin) {
lv_obj_del(winPin);
lv_slider_set_value(Slider, 0, LV_ANIM_OFF);
}
if (obj == CloseBtnCard) {
}
if (obj == CloseBtnDrive) {
lv_obj_del(winDrive);
}// endif
if (obj == CloseBtnNav) {
lv_obj_del(winNav);
WindowBool = false;
} // endif
}
}
}
Screenshot and/or video
This is a video of the problem (i press the number 9 to update, I dont think it’s the reason it crashes)
