    Hi, Quote from vikramtathe: “I have one more question that, Is it possible to adjust the spacing between the paragraphs? ” yes, since you are going to display strings in rectangles (GUI_RECT), you can define the position of the rectangles and thus…

    Hi, title and description with different colors/fonts in one line won't be easy to achieve. I'm not saying it is impossible, but it will be a lot of fiddling. So you might want to change your design, like the title could be placed above the text, so…
  • Hi, you have to make sure that the window that shows the text gets redrawn again. If you just display text, e.g. in your main task, and something else is drawn above the text, the text will be gone because it will not be redrawn again. I'm assuming you…

    Hi, sorry for the late response. There are a few flaws in your code. First, it is necessary to call GUI_Init() in your main task to initialize emWin. Then, it doesn't really make sense to set a callback that only calls the default callback. But this…

    Hi, I can't exactly picture what is happening on your screen, it sounds like something is wrong in your window structure. The MULTIPAGE widget could be useful for your application. It is basically a window with multiple child windows that can be…

    Hi, unfortunately I cannot offer you any kind of sample. To send and read data to/from the LCD controller, you have to set the function pointers in the structure GUI_PORT_API with routines that send a command (pfWrite8_A0), send one byte (pfWrite8_A1),…

    Hi, the PROGBAR widget has not (yet) been added to the AppWizard. However, it is possible to add any emWin widgets to AppWizard applications. To do that, export the code of the AppWizard project and go to the slot routine file located in the project…

    Hi, I didn't find anything unusual. But once again I couldn't execute it because there were files missing. Can you try to reproduce that behavior in a 'stand-alone' sample, ideally in one file? Thanks and best regards, Florian

    Replied to the thread ICONVIEW with transparent Background.

    Post
    Hi, the bug that items of an ICONVIEW could not have transparent backgrounds has already been fixed with emWin V6.10h. You could clear the selection with ICONVIEW_SetSel(hIcon, -1). Quote from JanBurg: “May be using ICONVIEW is the wrong approach…

    Hi, this is strange. I attached the sample that worked for me. I assume, the background behind your iconview isn't red? And could you tell me, which version of emWin you are using? Thanks and best regards, Florian

    Replied to the thread ICONVIEW with transparent Background.

    Post
    Hello, you have to make sure that the ICONVIEW is a transparent window. To do this, add the WM_CF_HASTRANS flag to the widget's create flags or call WM_SetHasTrans(hIconview). When this is done, the call ICONVIEW_SetBkColor(hIcon, ICONVIEW_CI_BK,…

    Hi, it looks like there's a cache problem. It is necessary to call SCB_CleanInvalidateDCache() before each DMA operation. Attached is a configuration for the STM32F746 board which is similar to your hardware and has therefore a good chance of working…

    Hi, does the window with the button always get deleted? If not, emWin will allocate memory every time a new button is created and every time a string is added. Best regards, Florian

    Hi, to keep the graph data, the dialog that contains the graph handles should not be deleted. You could hide the graph dialog when switching to another window and show the graph dialog again when opening it. So instead of deleting the windows and…
