[Can't get Image to display in simple List]

Hi All,

I am attempting to get the simple uGFX List code example to also show an image.

Below is my code, as well as defines added to gfxconf.h.

The list is displayed just fine, but no image in the list.

Is there something I'm missing?

 

I have defined the following in gfxconf.h:

GFX_USE_GDISP

GDISP_NEED_IMAGE

GWIN_NEED_LIST

GWIN_NEED_LIST_IMAGES

 

And here's my code:

#include <string.h>
#include "gfx.h"

static GListener gl;
static GHandle   ghList1;
static gdispImage img1;

static void createWidgets(void) {
    GWidgetInit wi;

    // Apply some default values for GWIN
    gwinWidgetClearInit(&wi);
    wi.customDraw = 0;
    wi.customParam = 0;
    wi.customStyle = 0;
    wi.g.show = FALSE;

    // Apply the list parameters
    wi.g.width = 200;
    wi.g.height = 100;
    wi.g.y = 10;
    wi.g.x = 10;
    wi.text = "List Name";

    // Create the actual list
    ghList1 = gwinListCreate(NULL, &wi, FALSE);
}

int main(void) {
    uint16_t    i;
    char        item[20];
    GEvent        *pe;

    // Initialize the display
    gfxInit();

    // Set the widget defaults
    gwinSetDefaultFont(gdispOpenFont("UI2"));
    gwinSetDefaultStyle(&WhiteWidgetStyle, FALSE);
    gdispClear(White);

    // Attach the mouse input
    //gwinAttachMouse(0);

    // create the widget
    createWidgets();

    // We want to listen for widget events
    geventListenerInit(&gl);
    gwinAttachListener(&gl);

    // Add some items to the list widget
    for (i = 0; i < 100; i++) {
        sprintf(item, "Item Nr.: %d", i);
        gwinListAddItem(ghList1, item, TRUE);
    }
    gdispImageOpenFile(&img1, "star16.gif");
    gwinListItemSetImage(ghList1, 0, &img1);

    // Make the list visible
    gwinSetVisible(ghList1, TRUE);

    while (1) {
        // Get an Event
        pe = geventEventWait(&gl, TIME_INFINITE);
    }

    return 0;
}

 

Much thanks in advance,

[How to get keyboard and mouse access to List for scrolling]

I am new to uGFX and currently trying to learn a little about Lists.  Trying to gain access to scrolling of the demo list program via keyboard and mouse.  I have the demo program from https://wiki.ugfx.io/index.php/List setup, compiling and running in a Win10 environment using gcc.  When first setting up the demo program, was getting build errors with the line in main.c... gwinAttachMouse(0).  Read elsewhere that was no longer needed, so commented that line and got past the build errors.  However, I have not yet figured out how to get access to scrolling the list up/down using my desktop's keyboard or mouse.  Any suggestions on how to accomplish this?

Thanks in advance for your assistance.

[Any version of µGFX-Studio available?]

Thanks for your reply.  I've also been trying to evaluate UI but having trouble getting anything going with this also.  Where might I find info on how to set everything up on a Win10 environment?

[Any version of µGFX-Studio available?]

Same for me.  Any information anyone?
