on the generated code for the label i not see the setup for the 'enabled' parameter

Can you be a bit more specific on this one? I just gave it a look and it seems like everything is like it is supposed to be.

Note that in the generated code gwinDisable() is only called when the 'Enabled' checkbox in the widget editor is not checked as widgets are enabled by default.

~ Tectu

i look too quick the generated code, and i not see the gwinDisable(), now i understand how the label are en/disabled :roll: my question was about this.

[Beta]

about the problem of 'generate', seems random, i not have investigated so much, but my impression is that some boolean flag remain not initialized or cleaned (inside the code of the studio) in some condition, and part of the files are generated.

i say this becouse i see happen if i press continously generate , 1st 'generate' make only 2 files, the 2nd 'generate' make all files, 3rd 2 files, 4th all files, but not ever... my 2 cent

i give lot of work to the uGFX team

1 problem solved, images.

1 have 2 files (rom_files.h)

1 in the root of the project to load audio data

1 in the output directory of the project (is in subdir inside the project) wich contains binary datas of images

i must merge the 2nd with the first and all is ok, no confort (i must remember everytime when i do update on the gui), but ok

1 tips

if i have 2 buttons (on different pages) that use the same image (ex: logout.gif)

after generate the romfiles.h contains 2 include at the same image (src/logout.gif) instead of 1

[Beta]

the problem was on the name of the image files, i changed the names (leaved blank & -)and now i can compile (i'm on windows with embitz)

a small problem, if outside the program i change the image (resize), the program show me the new image/size, but the button remain with the old size, i must change the 'custom draw' and size become correct

is possible for button widget add property that specify position of the text inside the button?

in my case i want show image, but text must be on the bottom of image, now stay in the center of image, also i can't specify the foreground/background

in the widgetstyle designer, can be very interesting if i can add new style from an existent style, so i can modify only the little things that i need without reenter all the parameters, this speed up much more creation of styles

on the generated code for the label i not see the setup for the 'enabled' parameter

another question, for what is intended the 'custom parameter' ? arbitrary data to pass for event handler?

another thing, if i press 'generate' (before i clean all the files on the output directory), sometimes happen that is writed only 2 files (main_sample.c, romfs_files.h) and 1 directory (rsc, with all the resource files), all the other files not, i must press another time 'generate' and all the files are generated.

i try now on my board (custom with ili9341 display), and i can see text of labels, but not the images of buttons, if i do the preview inside the studio i see all correctly..

before i use buttons as simple button and all was ok

inside the .zip file there are images of studio, of display output & the studio project

thanks

added an imagebox (with image) (with vs 0.12)

now i get this error

display 320x240, if i put label with this coordinate x=0 y=226 w=320, h=14 , save project, close program, the next time i open the project i found the label at y=220

[PWM Audio]

and was like this, but i must put on first place the path to the files..

[PWM Audio]

done, the first path in the makefile must be where is the romfs_files, otherwise search for the files fails..

[PWM Audio]

found the problem, is a path problem, i put an absolute path on include inside gfile\gfile_fs_rom.c (i know is really not good idea, but i want found the problem), and now the file is found, read, and i hope also played

on the makefile there are the path to the files romfs_files.h, so i not understand why is not included... must investigate more

[PWM Audio]

the function ROMOpen not found the file in ROM, all the parameters seems good, so i think the files are not included on compilation

there are some particular things to do, to use GFILE functions? maybe i forgot some particular, i have enabled this 'flags'

#define GFILE_NEED_NATIVEFS     FALSE 
#define GFILE_NEED_ROMFS        TRUE

#define GFX_USE_GAUDIO			TRUE

on chibios (3.0.3) i do nothing, to compile i use makefile, maybe this do some difference? compilation not show errors, and firmware correctly work

[PWM Audio]

#define MY_PLAY_FILE "allwrong.wav"

removed the inclusion and add #warning to romfs_files.h

no warning message shown

can be my makefile? the path to romfs_files.h there are

[PWM Audio]

ok, done, but i have problem to load the file from ROM

gfxBufferAlloc is ok

when i try to open the file with gfileOpen, function fail (tryed with 'r' & 's')

i have used the same file on the example dir of demos\modules\gaudio\play-vs1053\

ronfs_files.h & romfs_allwrong.h

then included the file on the main.c with #include "romfs_files.h" (the bin file become more big, so datas are on the rom)

#define GFILE_NEED_NATIVEFS FALSE 
#define GFILE_NEED_ROMFS TRUE

#define GFX_USE_GAUDIO			TRUE
#define GFX_USE_GFILE			TRUE
#define GAUDIO_NEED_PLAY		TRUE
#define GAUDIO_NEED_RECORD		FALSE
#define GQUEUE_NEED_BUFFERS     TRUE
#define GQUEUE_NEED_GSYNC       TRUE

.....

    if (!gfxBufferAlloc(4, 512))
    {
        errmsg = "Err: No Memory";
        goto theend;
    }

repeatplay:
    // Open the wave file
    if (!(f = gfileOpen(MY_PLAY_FILE, "r")))
    {
        errmsg = "Err: Open WAV";
        goto theend;
    }

[PWM Audio]

i'm trying to use audio with ugfx, to be more precise, i want use a piezo buzzer controlled with pwm, i looked example play-vs1053, but not understand how to selected the type of hardware to use (VS1053,pwm,adc), in this example is loaded the file audio, played etc, but how to set the port where to send 'audio'?

there are other simple audio example with pwm? maybe i'm wrong but i not see

thanks

[Beta]

good to know this!

another request, possibility to align left/right/center on the label widget

[Beta]

some annotations

if you give same name to 2 different widgets on different pages, graphically nothing happen, but with code when you refer to 1 is possible that you change characteristics of the 2nd, better check on the studio if name of the widget already exists

after i have added listbox on page, when i compile now get this worning

thanks

[label color]

maybe stupid question, but how to change color of label text from code?

thanks

here there are

yes, #define GFILE_NEED_NATIVEFS FALSE solve the compilation error

1 small bug

if i insert icon file with - character, i get error when compile the generated code:

i found where is the problem, if i add imagebox on screen, when i compile i get error.

also another thing, if i press 'generate' the previous files are deleted, but not all the files are generated, i must press another time 'generate' and all is ok.

i use version 0.8

[Beta]

i had this problem

after some hours trying to understand why the compilation start make problem, i delete all the files made by uGfx studio and regenerated the files, now all the think goes well

i not know what (and if) i have changed something, but i think no, anyway, i write this maybe can help someone

p.s.: 4 requests for ugfx studio -> possibility to insert basic drawing (line, arc, box, etc) , when studio generate sources, possibility do separate all the screens in different files (now is all in one file) ,

import fonts, choose if insert main function or not on the generated files

thanks

[makefile & embitz]

today i have designed some screens with the ugfx studio, all ok, exported the files, removed the main from ugfx_gui.c and linked compile file on makefile

now when i compile i receive this error:

before this error, the compilation was ok, seems some library are missing..

[makefile & embitz]

compiled!

i have on makefile

GFXBOARD = MULTIBOARD_F407

but on board.h

#define BOARD_NAME "Multiboard F407"

changed to

#define BOARD_NAME "Multiboard_F407"

compile is ok

thank you tectu, now i must test how to include my program, not only ugfx & chibios.
