br64 Posted February 15, 2021 Report Share Posted February 15, 2021 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, br64 Link to comment Share on other sites More sharing options...

Joel Bodenmann Posted February 22, 2021 Report Share Posted February 22, 2021 Hi, Check the return code of gdispImageOpenFile(). It will tell you whether the image was loaded properly. The widget will not display the image if it wasn't loaded properly. In general I'd recommend you making sure that you can display the image using the imagebox widget before attempting to insert it into the list widget as this makes it easier to ensure that there are no underlying problems with the filesystem, image decoders and similar.
