  • Hi, The sample you are using hasn't been updated and would only work with the old ABGR color format. One of the differences between the ABGR and ARGB formats is that the alpha values are inverted. You are using the new ARGB format since you defined GUI_USE_ARGB to be 1. The sample creates a memory device using the GUICC_8888 color conversion, but it should be GUICC_M8888I when using the ARGB format. You can easily fix this by creating the data device as follows: C Source Code (1 line)The routine…

  • Hi, Using the latest AppWizard version (V1.10) you can move and resize a window requiring only a few interactions. To animate the window position, you can use the ANIMCOORD job. The size of a window can be animated using a variable. Basically you are "animating" the value of the variable using ANIMVALUE and reacting on VALUE_CHANGED to execute the job SETSIZE on the window. For the "Value" in the SETSIZE interaction parameters you can then use the size variable by clicking "Set variable". Attach…

  • Hi, If Century Gothic does not include Chinese characters, you would have to use a third-party tool to create your own custom font. As said above, the Font Converter is only able of merging font files of the same font, type and size. Best regards, Florian

  • Hi, animated sprites take up more memory while GIF files require less memory, but are heavier on performance because the file needs to be read and decompressed first. An easy way would be displaying an animated sprite using an animation that only runs a single time. If you prefer to use the GIF file, you can read the delay of a single frame using the routine GUI_GIF_GetImageInfo() or GUI_GIF_GetImageInfoEx(). You could hide the IMAGE widget when the total delay of all frames is over. Best regard…

  • Hi, Virtual screens are an obsolete feature. What you want to do can be achieved by creating a large window (e.g. two times the horizontal size of your display) and using motion support for scrolling through the window. The Window Manager is a requirement for this, though. Our wiki provides an example that demonstrates how this can be done. Best regards, Florian

  • Hi, Which version of AppWizard are you currently using? If you are using an older version, the error might have been fixed already. You can download the current version of AppWizard Trial V1.10_6.14g on our website. The main purpose of variables is to be used from outside of AppWizard. Using variables and interactions, you can change the visibility of an object by setting a variable using APPW_SetVarData(). Best regards, Florian

  • Hi, the functions needed to run AppWizard projects are already included in the AppWizard. You can evaluate the tool by downloading the trial version that you can find on our website. However, the trial version does not include BSPs, therefore you only be able to run the project in the simulation, but not on a hardware target. To run AppWizard projects on a target, the full version is required which is included in an emWin PRO shipment. Best regards, Florian

    Hi, you can save a font as an XBF file to store it on external memory. If the external memory is inaccessible, you will need a file system to access and read the files. Quote from anuj.tanksali: “Also is there a way to generate a single font file with all the sizes and fonts. ” The output font file always contains characters that are of the same font, the same size and of the same font face (bold, italic, etc.). For example if you had "Roboto, 30, bold" and "Roboto, italic, 22", it would not be …

  • Hi, It is hard to say what is causing this behavior without any reference points. Could you provide an example to reproduce the behavior you are describing? Thanks in advance! Best regards, Florian

  • Hi, the GUI_Edit...() functions are old functions that do not give any visual feedback on the screen. It's better to use an EDIT widget that is in decimal mode. You can create an EDIT and call EDIT_SetDecMode() to activate decimal mode. The EDIT also provides equivalent functions for binary mode, float mode, etc. Best regards, Florian

    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 called after the MainTask finished. 2. You also have to initialize emFile and mount the external volume. Once again, have a closer look at the XBF font sample, the file is read exactly the same way. Best regards, Florian

  • 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 too good, it might make sense to use a normal window instead and display the animation by drawing each frame as a bitmap, like I mentioned above. See the attached example to see how this can be done. For 2D-drawings it would make sense to create a wi…

  • 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, you could redraw each drawing as you would like by invalidating the respective window. Best regards, Florian

  • 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 WM_InvalidateRect(). WM_InvalidateArea() redraws the specified area, but for all windows that are within the given area. When you're invalidating a rectangle/an area, the WM_PAINT case of the affected window (or windows) is executed as normal, except that th…

  • 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 the index of one image to be drawn is, the longer it could take as well, since the search for the sub-image takes longer. To increase performance, I would suggest to convert and save the sub-images as C bitmaps or external XBF files, if your target …

  • 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 in your application that draws a rounded rectangle. Add an interaction for your screen on INITDIALOG and set NULL as the job (e.g. ID_SCREEN_0 -> INITDIALOG -> NULL). This will generate a slot routine in the slot file of the screen, where you can …

    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 font. This is because, every time the font is redrawn (like when a widget uses it), the pixel data of the font is read from the file. When the font is not needed anymore (e.g. when the widget is deleted), GUI_XBF_DeleteFont() can be called and the…

    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 sample by replacing the Win32-functions by the equal functions provided by the target file system you are going to use. You can find an example in the SEGGER Wiki that demonstrates how external XBF fonts can be used in emWin, demonstrated via both …

    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, if choosing the "True color with alpha" format, the bitmap will be saved in the 32bpp format without a palette. Best regards, Florian

  • 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, please let us know. Best regards, Florian
