For example correct buttons, need correct code from this place:
7120: txt.h_space = 2;
7121: txt.v_space = 2;
to
7120: txt.h_space = btn->h_space;
7121: txt.v_space = btn->v_space;
e.g. for CheckBoxes

Hello, I try to implemente ugui with arduino/teensy 3.2, but unfortunately if I implement in the sketch #include "ugui.c" I get follow error:

invalid conversion from 'void*' to 'void ()(UG_COLOR) {aka void ()(long unsigned int)}' [-fpermissive]

?? whats wrong?

Seems that the UG_Init isn't documented. Given that nothing works without it, this seems like a critical oversight. Not hard to figure out from the source, but it 's still sort of a pain.

Not Every device has touch screen.

in my project, PRESS and RELEASE are working well, but CLICK is never normally working

Hi,
I am tring to built ugui to stm8l151and use STVD.but i got a error "a cast operator is attempting to reduce the size of a pointer", the error is at blow function:

UG_DriverRegister(DRIVER_DRAW_LINE,(void*)HW_DrawLine);

i don't know the root cause,can you help me?

hi all ,
how to create font for monochrome ?

UGUI default for the RGB888/565 lcd.
so how to add font for the monochrome lcd(like ssd1306)

void _UG_PutChar( char chr, UG_S16 x, UG_S16 y, UG_COLOR fc, UG_COLOR bc, const UG_FONT* font)

HW:
SSD1306 monochrome

Hi

Am I right that UG does not support font kerning? The thing where an I is smaller then an O. Does every letter uses the same width?

Is there some pre-work since I'm very likely going to implement that.

good job, thanks for yours ugui!

Hi,
Following is my code on Arduino IDE using ATMEGA2560 Board.
`#include <SPI.h>
#include "ugui.h"
#include "ugui_config.h"

#define DISPLAY_WIDTH 160
#define DISPLAY_HEIGHT 128

#define MAX_OBJECTS 10
#define BuffOUT 40

char bufferOut[BuffOUT];
void window_1_callback(UG_MESSAGE *msg);
UG_GUI gui1963;
UG_COLOR color[3];

void my_int_func(UG_S16 x,UG_S16 y,UG_COLOR z)
{
unsigned int sum=0;
sum=x+y+z;
}

void setup()
{
void (*foo)(UG_S16,UG_S16,UG_COLOR);
foo = &my_int_func;

UG_Init(&gui1963, foo(2,2,3), 160, 128); 

UG_COLOR color[3];        
UG_WINDOW window_1;
UG_BUTTON button_1;
UG_BUTTON button_2;
UG_BUTTON button_3;
UG_TEXTBOX textbox_1;
UG_OBJECT obj_buff_wnd_1[MAX_OBJECTS];

UG_Init(&gui1963, foo(2,2,3), 160, 128);    

}

void loop()
{
// put your main code here, to run repeatedly:

}`

I encounter following error when compiling. Kindly provide an insight of whats going wrong?

testugui:27:43: error: invalid use of void expression

 UG_Init(&gui1963, foo(2,2,3), 160, 128);
                                       ^

testugui:37:43: error: invalid use of void expression

 UG_Init(&gui1963, foo(2,2,3), 160, 128);

Regards,

So I offer a reformatted version
of it at my second, messy, what-ever-goes-style of GitHub account.

In UG_DrawBMP(),
invalid color conversion done when BMP format is 565.

just before this line the color is set to 888 format, but that causes wrong colors to be displayed on a 565 format screen
https://github.com/achimdoebler/UGUI/blob/master/ugui.c#L5840

a possible fix:

         tmp = *p++;
         #ifdef USE_COLOR_RGB565
            UG_DrawPixel( xp++ , yp , tmp );
         #else
            /* Convert RGB565 to RGB888 */
            r = (tmp>>11)&0x1F;
            r<<=3;
            g = (tmp>>5)&0x3F;
            g<<=2;
            b = (tmp)&0x1F;
            b<<=3;
            c = ((UG_COLOR)r<<16) | ((UG_COLOR)g<<8) | (UG_COLOR)b;
            UG_DrawPixel( xp++ , yp , c );
         #endif

Hi guys,
I am working with ssd1963 display, with arm cortex m4. I have ported ugui for my display and test all the basics functions. They are working fine for me but when I am trying to create a window as per written in reference guide, it is no showing anything. Any help in this regards 'll be highly appreciable.
Thanks.

Dear my friends:

In the code , there are the define of DRIVER_FILL_AREA, but there are no samples , how to write the porting code .
I tried some ,but faild
The uGUI has too many forks and too many changes.
Can anyone helps?
THANKS.
sorry for my pool english, hope you can get my point and Thanks for you time reading this. :)

Does anyone recommend what could be used to create UG_BMP ?

v0.31 beta commit contains changes from forked repositories. The proper way to include those changes would have been a merge/pull request. The corresponding changes need to be merged in for visibility in Git.

In line 5650:

msg.src = &obj;

Instance where a stack address is assigned to a non-local variable. Storing the address of a local variable in non-local memory can cause a dangling pointer bug if the address is used after the function returns.

Dear:

The uGUi is really great project! it is powerful~!
When I use this I can't find the place to set it into grayscale or mono mode?
I think maybe there are missing ?
Thanks for your time and Thanks for your reply if there are.
:)

UG_PutString, as with most other functions, has the location first, then the object, and also use the previously set colors.
UG_PutChar, on the other hand, has the object first, then the location, and then color information.
This makes for an inconsistent UI.

What does it take to make to make uGUI work with ILI9341 + ESP32 ESP-IDF ?
Any pointers highly appreciated.

Without

#ifdef __cplusplus
extern "C" {
#endif // __cplusplus

at the beginning and later proper closing the library will not compile in C++ project.

Hello guys!

First of all many tanks to @achimdoebler , this is a very time saver library!

The only big problem (in my case) is that i'm trying to use it together with Arduino Adafruit_GFX and a modified version of Adafruit_ILI9341 libraries but, after compiling and uploading on my Arduino Uno with 2.4 tft lcd shield (8bit bus and 18bit colors) , what appears is a randomly colored pixels on the screen.

All examples on the Adafruit libraries work well so, i think i'm doing something wrong with the implementation of the uGUI lib.

My code is as following:
In my EXAMPLE i modified the ugui_config.h and i've included all relevant code in guitest.ino.
Then, in the UGUI.h file i replaced #include <system.h> with #include <Arduino.h>.

Someone has already tried to run the library with Arduino?
In that case you could post your implementation code?

Many thanks.

UG_PutString, as with most other functions, has the location first, then the object.
UG_PutChar, on the other hand, has the object first, then the location.
Additionally UG_PutChar sets the foreground&background colors, but UG_PutString does not have any color information. Other graphics primitives have only the foreground color.
This makes for an inconsistent UI.

Comment would help if you're supposed to adapt this.

hi i am planning on using the uGUI for the ST7529 driver using MSP430.
Can you please share the example for how to define the pset function ?

I have gone through the Manual PDF and also the ST7529 datasheet.

I am unable to understand how to define the PSET function.

If someone could help me on this, please.

ugui works well right now ,but i can not rotate display .sometimes i need this feature, is there any way to achieve that goal?

Any demand / existing implementations / caveats adding UTF-8 support for uGUI (like in https://github.com/olikraus/u8g2)?

hi all,
how can set Font Direction (rotate 45 degrees)

in my design , it is Diamond . so all component need align direction.

LCM ST7571,128x128

I suggest we extend UG_FONT definition with two constants: offset and length. The reason is that if i needed an incomplete character set, for example just numbers, i wouldn't spend ROM space for keeping the rest of the characters. Offset and length means the font defines characters starting from ascii code "offset" and ending by "offset + length"

Currently uGUI only has support for a single touch point, however certain dev boards with capacitive touch sensors (the STM32F7-Discovery, for example) have up to 5 or more points that may be activated simultaneously. While the simple solution is to just pass all 5 (or more/less) in one at a time, I think there is room for growth of uGUI in such a way that these multi-touch events could be used to add additional functionality. One such example is rotating a window, where two touch points could be used to adjust the rendering of the window to make it appear rotated, leading to a potentially improved experience and greater usefulness. Not strictly necessary, but something to consider I think.

I'm doing calls to UG_FillRoundFrame and UG_DrawRoundFrame with the same params, but radius of the corners seems to be different. Making call with radius 3 is handled right by UG_FillRoundFrame but UG_DrawRoundFrame seems to draw frame with radius 1.

Hello,

Could you please provide the guide in a text format such as markdown, plain text, or on the github wiki?

When using the PDF it's not possible (at least on OS X) to copy any of the code examples since some character such as underlines appear to be missed for some reason... I've tried both the Chrome and Preview viewers but neither of them really works.

Thanks :)

Hi,

I am plagued by that I have to flash the code into the MCU to check the result of GUI everytime.
So is there anyway or will there be a way like simulation on linux to solve this problem?
Thanks a lot!

Given this project seems no longer alive, I'm providing the fork for anyone who might be searching new enhancements...

I can not find any info of checkbox. I look through wed, guild book and source commit. I just donot know what is the main point of checkbox ,and what is the function it will show to us?

A newbie who familer to android always think that callback function will be called when the button pressed ranthre than changed. So i suggest add a new conditional sentence in the callback function (in your demo).

ex: if ( msg->id == OBJ_TYPE_BUTTON && msg->event == OBJ_EVENT_PRESSED )

i spent whole two days to figure this future out. ～(￣▽￣～)
