    Replied to the thread Create chinese font.

    Post
    Hi, I noticed a few things: 1. You must not comment out the super-loop in your main-task when using the Window Manager. This will only work when only using GUI_... functions in the MainTask. Otherwise emWin isn't kept alive and no more routines will be…

    Replied to the thread Handle redraw of specific parts of a dialog.

    Post
    Hi, widgets are essentially windows, but each with specific "widget properties" (like button color etc.). For the GIF animation it would normally make sense to use an IMAGE widget. But since you mentioned that the performance of the animation wasn't…

    Hi, when calling WM_InvalidateRect() with the area specified to one of your drawings, only the parts in the area should be redrawed, as mentioned above. Is it possible to create a separate window for each of the three drawings you want to do? That way,…

    Post
    Hi, a WM_PAINT case handles all the drawing operations that are done in a window. So you don't have to consider in the WM_PAINT case, which parts of the window you want to redraw. If you want to redraw a certain part of a window, you can use…

    Hi, drawing of GIF images can become quite slow, depending on the GIF image. The more colors differ in a horizontal line, the longer it takes to draw the image. An animated gradient for example would have a big impact on performance. Also, the higher…

    Replied to the thread Rounding the corners of a Box object in AppWizard.

    Post
    Hi, unfortunately, the AppWizard does not currently offer the possibility to draw rounded rectangles via the Box object. But such a feature definitely makes sense and we will consider adding it with a future release. As for now, you can create a window…

    Hi, since a regular GUI_FONT is created from the XBF-file, the font can be used at any point where a font can be set, including widgets. Though it is crucial the pointers to GUI_FONT and GUI_XBF_DATA stay valid and the file is kept open while using the…

    Replied to the thread Create chinese font.

    Post
    Hi, CreateFile() is a function provided by the Win32-API. It is used in the above example so it can be run in the emWin simulation on Windows. If you want to use an XBF font from external memory, your target needs a file system. You can then adapt the…

    Replied to the thread Bitmap converter.

    Post
    Hi Pieter, The issue of incorrect output has been fixed since v5.50. You should note, when converting to best palette, the bitmap will be palette-based. This means, you will have to save the bitmap in an indexed format, such as 8bpp or RLE8. Otherwise,…

    Replied to the thread emWin Migration/Update to latest version v6.14.

    Post
    Hi, emWin v5.44 is three years old, but you should be able to update without complications. We're keeping in mind to keep old code compatible, e.g. by adding a macro if a function is removed or renamed. If you encounter any problems when updating,…

    Replied to the thread WM_DeleteWindow() during WM_TOUCH_CHILD processing.

    Post
    Hi, I was able to reproduce your issue. You are correct, the error occurs because the window still receives messages after being deleted. You can react on WM_TOUCH in the window that is to be deleted. When the window is touched and the state is…

    Replied to the thread How to get Theta symbol in AppWizard?.

    Post
    Hi, you can simply add the symbol to the text of the object. Then you will have to edit the codepoints of the fonts used for the project. This determines which characters will be included in the font. Go to Edit -> Preferences -> Edit default…

    Replied to the thread Bitmap Converter(ST) format RLE16 with transparency.

    Post
    Hi, You can convert an image into 'best palette with transparency', but you should note that only 1 bit will be used to store the transparency. This means semi-transparency is not possible. An image with 'best palette (and transparency)' can be saved as…

    Replied to the thread MEMDEV Issue...

    Post
    Hi, first of all, you should make sure that GUI_Init() has been called at the beginning of your program. Then, after your drawing operations in a memory device are finished, you have to deselect the memory device by calling GUI_MEMDEV_Select(0). If…

    Hi, Did you make sure the VNC module files have been added to your solution? You should also check your include paths if they include GUI_VNC.h. Best regards, Florian

    Hi, You can view and interact with your emWin application from your PC by the use of a VNC server. Note that emWin VNC routines are part of an additional module. Have a look at this example to learn how to start a VNC server from your board. Your board…
  • Hi, the only way to do this with a YT graph is by clearing the data array when the limit has been reached. Then, newly added points will appear on the left side of the GRAPH again. You can clear the data object by calling GRAPH_DATA_YT_Clear(). Best…

    Replied to the thread Display Text box on Image Widget.

    Post
    Hi, the easiest way would be to create a TEXT widget and place it above the IMAGE widget. If you want the TEXT widget to be drawn transparently (without a background), you can add the WM_CF_HASTRANS flag upon creation of the TEXT widget, or call…

    Post
    Hi, if you are using the same color conversion mode there's still a difference, then it is related to your target LCD. I have attached a sample for testing colors on a display. Best regards, Florian
  • Hi, can you provide me with your emWin version number and some code to reproduce the behavior? Best regards, Florian
