(I know you told me to post on a forum, but I couldn't find one that could 
"help")

How can I exit the GUI, go to a console?
For example, I'm trying to implement ELF/DOL launching, and to do that, I need 
to exit the GUI, call the launch function, and then restart the GUI.

Also, when I exit, I want to print "Exiting" to the screen.
However, when I exit, the screen turns black for a second, and returns to the 
Homebrew Channel.

Code:
int
main(int argc, char *argv[])
{
    InitVideo(); // Initialize video
    SetupPads(); // Initialize input
    InitAudio(); // Initialize audio
    fatInitDefault(); // Initialize file system
    InitFreeType((u8*)font_ttf, font_ttf_size); // Initialize font system
    InitGUIThreads(); // Initialize GUI

    DefaultSettings();
    MainMenu(MENU_SETTINGS);

    VIDEO_Init();

    WPAD_Init();

    rmode = VIDEO_GetPreferredMode(NULL);

    xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));

    console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

    VIDEO_Configure(rmode);

    VIDEO_SetNextFramebuffer(xfb);

    VIDEO_SetBlack(FALSE);

    VIDEO_Flush();

    VIDEO_WaitVSync();
    if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();

    printf("\x1b[2;0H");

    printf("\n\n\n\n\n\n\nGUI Exited.\n");
    printf("Press any key to exit...\n");

    while(true)
    {
        printf(" ... ");
        sleep(500);

        WPAD_ScanPads();

        u32 pressed = WPAD_ButtonsDown(0);

        if(pressed)
            exit(0);

        VIDEO_WaitVSync();
    }

    return 0;
}

What steps will reproduce the problem?
1. Trying to compile the library

What is the expected output? What do you see instead?
Expected successful compiling. Instead gives error about Vector-type.

What version of the product are you using? On what operating system?
libogc rev. 3665 (latest) and libwiigui rev. 24 (latest)

Please provide any additional information below.
In libogc svn the Vector has been renamed to guVector and thus you're
unable to compile current svn of libwiigui with svn of libogc.

Attachment includes patch to rename Vector to guVector

What steps will reproduce the problem?

1. Install Devkit and the libogc from this page
2. Download libwiigui 1.04 and open the project
3. Compile the project

What is the expected output? What do you see instead?

When I compile the project I get some errors.
Here the output:

What version of the product are you using? On what operating system?

I used version 1.04 on Windows Vista Home Premium 32Bit


Please provide any additional information below.

With version 1.03 I have no compile errors and all worked fine.

greetings, Strece

hi

Could you guys add a over button info or over browser info. What i mean is
that if you stay over a button or browser option for like 3 secs a small
info appears, like in Wii Systemmenu. 
That would be great.

Thanks in advance.

using the last libwiigui
encoutered some problem when more than one cursor are on screen
some button don't grow and some others don't click by one cursor but the 
other work
can't find why

here a link to my sources
http://code.google.com/p/savegame-manager-gx/updates/list

that will be very good if u could just help me a little bit
my knowledge are very little and will be very happy if u could explain to 
me where i'm wrong

thx in advance

Could you may add a simple ProgressWindow into your example application?
I am able to use everything whats in there but the ProgressWindow from
Snes9GX seems to complicated for me at the moment.
In my case I just have a WindowPrompt, the user clicks on "OK" and then I
have a process which returns values from 0 to 100.
So, a little sample code which just adds this (Title, message, ProgressBar)
into a window would be very handy.

Hi all, i may find a bug in libwiigui.
Before i want to say that i'm running the last rev of devkit pro (r21) and 
libogc 1.8.3 plus all my portlibs etc are up to date.

Firstly, i've made a little program (template.c attachment) with the strict 
minimum to make the balance board work (helloworld template + bb stuff)
I print out the weight and it works just fine.

Secondly, i took the libwiigui template and replace the content of the while 
loop in MainMenu (menu.cpp) by the bb stuff. The result is really out of sense 
because the weight give approximatively -232kg.

Since the bb code stuff is exactly the same i assume that the problem is in 
libwiigui (some kind of interference or i don't know) but i may be wrong.
Please let me know if it 

While in some places GuiWindow seem to accept 2^32 children [1], in most
places the maximum number of children is implicitely 2^8 [2].

Since 2^8 was insufficient for my need (2^16 would have been enough tho), i
figured it might eventually also be the case for others. Thus, here's a
patch that brings up the limit to 2^16. (I doubt anyone will need 2^32
elements...)

[1] e.g.GetGuiElementAt(u32)
[2] e.g. Draw() and Update()

What version of the product are you using? On what operating system?
The patch was created against SVN HEAD (r49). I tested my code on my Wii.

I'm a lousy GUI designer, and therefore get a lot of requests for switching
to libwiigui, which absolutely everyone loves!

The problem I have is that I'm also a lousy coder and need a platform with
good tool support (debuggers etc) to develop on. I therefore try to make
all my programs build for both Wii and Linux, which is no problem since I'm
using SDL. Unfortunately, libwiigui isn't using SDL, so I can't easily keep
both debuggability and a nice GUI, and my users will keep on nagging me for
this.

So therefore, if possible and if you feel that you have the time: Porting
libwiigui to SDL and making it buildable on the host would be very nice!

Before I "installed" libpng to devkitPro, I kept getting "could not find png.h" 
errors.

So, I downloaded the .h and .c files in libpng-1.4.1 to the 
devkitPPC\powerpc-eabi-includes folder (i had no portlibs folder).

I compiled again, and this time, I got this error:
pngu.c
In file included from 
c:/Users/Administrator/Downloads/libwiigui-1.05/source/pngu.c:15:
c:\devkitpro\devkitppc\bin\../lib/gcc/powerpc-eabi/4.4.3/../../../../powerpc-eab
i/include/png.h:1137: error: expected specifier-qualifier-list before 'z_stream'

Solution please?

Hi,

Sorry to create an issue, but I didn't find another
way to contact you. There is another way to reach you? 

I started developing a homebrew for wii and found it very interesting
this library. I managed to make great progress. Thank you very much
to develop this library.

I have a question, I looked at the api documentation and not found. 
I was trying to draw more than one image at a GuiWindow, there is such
possibility?

Indeed I was wanting to put a background image with a watermark of
another image, on a given image x, y positions. (Example: screenwidth -
watermarkWidth - 10, screenheigth - watermarHeight - 10)

I believe it is possible to do this using a temporary image buffer,
But I could not accomplish.

Sorry for my bad english.

Thanks

What steps will reproduce the problem?
1. Make a GuiOptionBrowser
2. Try to drag the scrollbar

What is the expected output? What do you see instead?
It should scroll like in any normal GUI, instead, nothing happens

What version of the product are you using? On what operating system?
The SVN on the Wii

Please provide any additional information below.
I've been using Wiimote 2, since my Wiimotes are messed up and they keep 
getting ordered wrongly.

Nyko recently released a cordless version of the Classic Controller which
currently is not recognized by any homebrew applications. Any chance this
can be remedied? (I'd assume it's just an item code that needs to be added
to a list of recognized attachments)

FCC ID sqo87050r03

Serial # 87050-e14

Hi
it´s not a real issue but how do i make the OptioBrowser scrollable if i
click on the arrows nothing happens.

Takti

How about a Grayscale method for the GuiImage Class? If you would like to
add it here is how i did it:

void GuiImage::SetGrayscale(void)
{
    GXColor color;
    u32 offset, gray;

    for(int x = 0; x < width; x++) {
        for(int y = 0; y < height; y++) {
            offset = (((y >> 2)<<4)*this->GetWidth()) + ((x >> 2)<<6) +
(((y%4 << 2) + x%4 ) << 1);
            color.r = *(image+offset+1);
            color.g = *(image+offset+32);
            color.b = *(image+offset+33);

            gray = (77*color.r + 150*color.g + 28*color.b)/255;

            *(image+offset+1) = gray;
            *(image+offset+32) = gray;
            *(image+offset+33) = gray;


        }
    }
}

This is actually related to Snes9xGx for the Wii; this is regarding the tinny 
sound issue. Snes9xgx emulates snes audio at 32000Hz whereas when going to the 
menu (home button), it's fixed at 48000Hz. When you go back to the game (or the 
wii system menu) the sound becomes "tinny" or "raspy" (until you reset the wii 
or switch back and forth in the menu). Dborth (the author of Snes9xGx) has told 
me on numerous occasions that this is something that he cannot fix on his end, 
that it's an issue with libwii/libogc. Can this issue be resolved at all?

What steps will reproduce the problem?
1. loading a png file from sd card with fopen

What is the expected output? What do you see instead?
Should show a clean image but only shows it scrambled

What version of the product are you using? On what operating system?
The actual SVN

Please provide any additional information below.

That´s how i try to doing it at the moment

u8 *imgsd;
static u32 imgsd_size;

int loadimg(char * filename)
{
    FILE *fp;
    u32 filesize;
    u32 ret;
    char filepath[128];

    ret = fatInitDefault();
    if (!ret) {
        return 0;
    }
    sprintf(filepath,filename);

    fp = fopen(filepath, "rb");
    if (!fp) {
        return 0;
    }
    fseek(fp, 0, SEEK_END);
    filesize = ftell(fp);
    fseek(fp, 0, SEEK_SET);

    imgsd= (u8*)malloc (sizeof(u8)*filesize);
    if (imgsd== 0)
    {
        //printf("ERROR: Out of memory\n");
        return 0;
    }

    memset(imgsd,0,filesize);
    if(cover == 0){
        fclose(fp);
        return 0;
    }
    char size[30];

    ret = fread(imgsd, 1, filesize, fp);
    if(ret != filesize){    
        free(imgsd);
        fclose(fp);
        return 0;
    }
    imgsd_size = filesize;
return 1;
}


static int menu()
{
...
    if (loadimg("noimage") != 0)
    {
    GuiImageData coverimgdata((const u8*)cover);
        CoverImg = new GuiImage(&coverimgdata);
    CoverImg->SetAlignment(ALIGN_LEFT, ALIGN_TOP);
    CoverImg->SetPosition(50,200);
    }
...
}

Several times in gui_text.cpp, memory is released using delete instead of 
delete[]. I'm not sure if this is leaking memory or corrupting the heap, 
but it's almost certainly not doing anything good.

Steps:

1. Extracted libwiigui's zipfile to a folder called libwiigui 
2. Extracted the second zipfile somewhere else and copied everything to
respective folders on $DEVKITPRO/libogc/
3. On libwiigui/ , when trying to compile it, this happened:

$ make
audio.cpp
demo.cpp
In file included from /home/wendel/devkitpro/libwiigui/source/demo.cpp:18:
/home/wendel/devkitpro/libwiigui/source/FreeTypeGX.h:155:22: warning:

make[1]: *** [demo.o] Error 1
make: *** [build] Error 2


I can't find this ft2build.h file anywhere on my devkit or on these
extracted zipfiles. Looking on lines 155~157 of FreeTypeGX.h it looks like
it tries to include a file which name should be #define'd as FT_FREETYPE_H.
The respective #define is on include/freetype/config/ftheader.h , line 173;
and this ftheader.h file isn't #include'd anywhere on this project.

Please update FreeTypeGX.cpp to support utf-8.
I'm providing a patch for simplicity but note that after isolating the
issue I noticed that you actually updated that file already in WiiMC.

A user has suggested that i apply a patch to the video.cpp file in
libwiigui for my wiixplore project but the patch seems to cause a compile
error. Could you check it for me.
