Description
Same program on both,Simulator and target Board display differently
What MCU/Processor/Board and compiler are you using?
Target board:
STM32F769-DISC using STM32CubeIDE
Simulator (on windows 10):
Microsoft Visual Studio Community 2017
Version 15.5.2
VisualStudio.15.Release/15.5.2+27130.2010
Microsoft .NET Framework
Version 4.8.03752
What LVGL version are you using?
both 7.7.0 (CHANGELOG.md shows ## v7.7.0 (06.10.2020) but git tag shows 7.6.1)
What do you want to achieve?
Development on simulator and deployment on target board by copy my code from simulator project to the
board project
What have you tried so far?
Changing the LV_DPI to different values in lv_conf.h. This does affect the display but in a strange and inconsistent (for me) maner. Fx. increasing LV_DPI makes containers wider and higher, on a tab page
but tables remain the same. On a window object buttons get bigger in both h&w, dropdown list are unchanged, and text areas higher but vertical and horizontal distances are the same.
Code to reproduce
Show how I create text areas and position it (more code can be shown if needed)
//-------------------------------------
static lv_obj_t * create_numeric_field(
lv_obj_t *parent,
lv_obj_t *relObj,
const char *lbl_text,
uint16_t *field_ptr) {
char buf[TEXT_BUF_SIZE_LOCAL];
/* fiels text area */
lv_obj_t * ta = lv_textarea_create(parent, NULL);
lv_obj_set_event_cb(ta, ta_event_cb);
lv_textarea_set_accepted_chars(ta, NUMERIC_RANGE);
lv_textarea_set_cursor_hidden(ta, true);
lv_textarea_set_max_length(ta, 5);
lv_textarea_set_one_line(ta, true);
lv_obj_set_width(ta, 80);
lv_snprintf(buf, TEXT_BUF_SIZE_LOCAL, "%d", *field_ptr);
lv_textarea_set_text(ta, buf);
lv_obj_set_user_data(ta, field_ptr);
if (relObj == NULL) {
lv_obj_align(ta, NULL, LV_ALIGN_IN_TOP_LEFT, 250, 50);
}
else {
lv_obj_align(ta, relObj, LV_ALIGN_IN_TOP_LEFT, 0, 50);
}
/*field lable*/
lv_obj_t * f_lbl = lv_label_create(parent, NULL);
lv_label_set_text(f_lbl, lbl_text);
lv_coord_t obj_width = lv_obj_get_width(f_lbl);
lv_obj_align(f_lbl, ta, LV_ALIGN_IN_TOP_LEFT, -(obj_width + 10), 5);
return ta;
}
Screenshot and/or video
In the following screenshots ,The first two images(drawn on a tab) are shown equally in simulator ad target, The last two (drawon on a window object) are shown differently:
