  • Hi MikeFlyersFan, Much thanks for that, I will try it out tomorrow. Kind Regards MikeZ

  • Hi All, I realized the way I asked my question previously was not very clear. I have window which has a background image, on top which are widgets and some small bitmaps, working exactly as required. Three of the bitmaps I would like to appear 100% transparent normally, invisible, so the user does not see them, but when a flag is set they are opaque. Is this just the matter of setting the GUI_SetAlpha() to the appropriate value before drawing the bitmap, then re-setting after so nothing else is …

  • Hi All, I would like to display a small bitmap while a physical button is pressed, the rest of the time it is not shown. Appreciate any suggestions on how this might be done simply. Kind Regards MikeZ

    Hi, is it possible to create a horizontal list of radio buttons by grouping single radio buttons placed side by side. Will this work for more than 2 radio buttons and use the RADIO_SetGroupId() command. I would like 4 radio buttons place next to one another horizontally and only ever have on active at a time. Kind Regards MikeZ

    Hi All, I created a window with GUIBuilder with several widgets and a bitmaps, all displays fine on our custom board, all but the bitmap which does not show at all. I would appreciate any help which points me in the direction to resolve this problem. There is SDRAM on the board, so there is plenty of memory available. Kind Regarad MikeZ

  • Hi Sven, Thank you, I will check it out. Kind Regards MikeZ

  • Hi All, Forgive the poor subject description, I have small bitmap image in a window, I would like to have arrow/marker (upside down V) below its lower edge, which under control could be made to position itself anywhere along that lower edge. Where do you start to make something like this. Kind Regards MikeZ

  • Hi Sven/All, I sorted out the problem, I had misunderstood the process of setting up a custom callback and all the steps involved. There is an excellent related example on the forum CloseDropdownOnEscape.c that is very helpful together with the relevant section in the user manual. Kind Regards MikeZ

  • Hi Sven/All, Just to add little to my last message, it appears that the list box is not getting re-drawn incorrectly and appears blacked out , even so pressing one of the current external touch buttons the window changes to correct one in all cases. I created the windows in GUIBuilder. I have tested the custom Listbox callback on one window only, the rest of the window is drawn correctly. The custom callback only handles the WM_CODE and WM_IMAGE (not sure of WM_IMAGE details), I figured that all…

  • Hi Sven, I tried and it works, but the Listbox comes out as black rectangle, am I also suppose add the contents of the Listbox specific parts from my original windows/Dialog callback function to the new custom Listbox callback function. Kind Regards MikeZ

  • Hi Sven, Thanks for your response, I will try it out. I am very new to this type so still learning, the messages from the external touch buttons are to close the current window and open new one, what you are proposing is send to message to the Listview widget and process it in its callback function, am I correct in the this interpretation? Kind Regards MikeZ

  • Hi Sven, I do not know how to manually unfocus the list box without the redundant Button, with the Button I can use the command BUTTON_SetFocussable() before sending the key messages, but it is not pretty. Is there an equivalent command for the Listbox. Kind Regards MikeZ

  • Hi Sven, Thanks for your response. I had just added button which did nothing more than deselect the Listbox and program now worked as before, closing and opening a new window. I can alter the item selected in the Listbox, which I am doing with an external switch, but i should manually de-focus it before sending the key messages. Would the latter do the job of the deselect Listbox button I added. What commands are used for setting focus manually? thanks. Kind Regards MikeZ

  • Hi All, I have small program which has been working fine, it consists of 6 windows, whose opening and closing is controlled by custom touch buttons and using GUI_StoreKeyMsg. The windows now contain no buttons but listbox and text information which are controlled by external switches. From I have determined it appears to Focus problem, WM_KEY is not getting fired. Please what is the simplest way to resolve this Kind Regards MikeZ

    Hi Sven, Thanks for responding. I am using the STM32F429IIT6 attached to 8MB of SDRAM with a LCD OF resolution of 480x272, I am driving the RGB (8-bit) lines directly, as well as the VSYNC, HSYNC, DCLK AND DE. Thanks MikeZ

    Hi Sven, Thanks for your reply, I will look into the areas you suggest. The LCD has a resolution pf 480x272 and 8MB of SDRAM is available, so multibuffering should be possible. A question about GUIBuilder please, with Multipage, must I first place all the objects on page before I add another page. Also, is there way to anchor Multipage in a parent window. Thanks MikeZ

    Hi, I have an application which require at least six windows. I did some tests initial tests opening closing windows triggered by external touch buttons using GUI_StoreKeyMsg(), it worked fine, but you could just make out the screen changes (updates), since each window was a different colour. Is there a way to open all the windows and work with the one particular one at a time, hiding the rest. I would like seamless transition between windows. Secondly, I had thought about using the multi-page i…
