Hi,
I have an application which has been running nicely on Harrier and iMate devices, well any PPC devices really because of their rectangular screen shape.
My client has gone and bought some Palm Treo 700wx devices, and they have a smaller square screen.
In the resource of my project the screens are designed to fit PPC. When it runs on the Treo the Treo automatically pops up a scroll bar to allow the whole view to be seen.
The issue is when I first go into the app I can't see the top of the screen, about 20 odd pixels heigh aren't displayed. The scroll bar still displays and I can scroll down to the bottom of the view, and when I scroll up again the top of the screen is still out of sight.
If I exit the app just by tapping on the x in the top right corner (so the app is still running, not exiting properly via my Exit button which shuts down the app), I exit the app and then when I go back into the app the screens are displayed correctly, there is no missing space at the top of the screen.
If I exit the app via my exit button and then start the app again, the top of the view is missing again.
Does anyone know why the screen isn't displayed correctly when I first enter the app, or why it should come right when reloading the view again? Has anyone else had problems with screen layout when putting PPC apps on the square Treo 700wx?
Thanks
It sounds like you have a 'refresh' problem. I haven't encountered this my self and it is really hard to diagnose when you don't even tell us what language your app is written in, but basically here is what I think happens:
When your app is launched, part of its window doesn't get properly painted (not sure why exactly).
When you click the X the app isn't closed, but minimized.
When you return to it the window is maximized and repainted. Second repaint goes correctly.
The quick solution to this would be to force a window refresh just after the app is fully started.
Sorry I forgot to add the language.. it's written in eVC++ 3.0
I'll give the refresh a go, thanks
Further Questions..
I thought that minimising and then maximising the screen fixed the problem, but only partially..
Because the screen in resource is designed for regular PPC it is bigger than the Treo 700 screen size, so the OS automatically shows a scroll bar.
The new issue I'm seeing is to do with the scroll bar. The steps I take to reproduce the issue are:
1. Go to View1, and I scroll down the view (I'm using CView not CDialog)
2. Go to View2
3. Go back to View1. When I go back to the first view the scrollbar is scrolled down in the position I left it.
4. Scroll up to top of view and some of the controls in the wrong place. Some controls I dynamically create in OnInitialUpdate, and as part of the Create() I pass in CRect to tell it where to create the control.
If I set CRect.top to say 10, it's created 10 down from the top of the visible screen. The problem is that because I've scrolled the view previously the view draws it 10 down on the visible portion of the view.
I had thought that the easiest solution would be to always reset the scroll bar to the top of the view before creating my controls, but I'm not sure how to force the OS scroll bar to the top of the view. I've tried SetScrollPos(0,0) or ScrollWindow(0, y). ScrollWindow moves the actual view up or down, but the OS scrollbar is still in the same position.
Any ideas on how to set my view window to the top and to reset the scrollbar?
Thanks again
How to refresh a view?
I have sorted the issue mentioned just above, by finding the scroll position and factoring in that when I set the value of CRect area of the controls I need to dynamically draw.
I'm now just left with the first issue, of when I first start up the app the top part of the window and scrollbar are covered by the Title/Taskbar at the top of the screen.
If I close the app via the x button and restart the app, the issue resolves itself. Or if I open up any dlg like the About screen or even display an AfxMessageBox, when I close the dialog the original screen is redrawn correctly, in the correct position and scroll bar fully shown.
I have tried calling RecalcLayout(), RefreshWindow(), UpdateWindow(), Sending WM_SIZE messages and a whole range of things, but I can't seem to get the screen refreshing correctly apart from when I open any dialog and close that dialog.
When you close a dialog what messages get sent to the previous view that force it to redraw? Does anyone have any suggestions how I can force a refresh myself?
Thanks again
Did you try InvalidateRect?
I am getting a bit rusty with MFC, since I now try to do things the hard way and use pure win 32, but this should work.
If you can't use it as a class member, call the API directly using you view GetSafeHwnd() function for window handle). Use NULL for lpRect to redraw the whole window and FALSE for bErase to prevent flickering.
Note that UpdateWindow() only triggers repaint if part of the window becomes invalid (the contents needs redrawing).
No I hadn't thought of using InvalidateRect(), so I should give it a go.
In the end I just wanted the issue fixed so opted for a quick 'n dirty solution of displaying a temp CDialog as soon as the app starts and calling EndDialog() immediately in the OnInitDialog() so the dialog disappears before you see it.
It worked and the original screen gets updated to correct size, layout and scroll bar.
Cheers.
Running CM 7.1.0 on nook color with 1.3 ROM. I downloaded and installed App Brain market, Spare Parts, Nook Tweaks, and a couple of games (Bubble Breaker and Angry Birds). The matrix at the bottom center of the screen disappeared; I have rebooted multiple times.
There is now no way that I can find to get to the apps I downloaded -- I can see them with the app manager, but that won't let me launch them.
App Brain moved itself to the desktop(?), and I can launch it by tapping, but I cannot browse the apps. Where did I go wrong? Is App Brain a source to be avoided?
If I understand you correctly, this same thing baffled me upon my first run. You deleted the square box that opens the app drawer correct?
Long press empty area on home screen, and select launcher actions. Then select open/close app drawer. You can put it back in the dock by dragging it back to where it was when you first booted.
I was paranoid and a noob, so I made a spare for my home screen and kept it there for a week, until I realized I could just repeat that fix anytime I needed to.
Alternatively, you can program your swipe up or swipe down action to open/close your app deawer.
Thank you! I held on the background, selected Open/Close, and it showed up on the home screen. Then I dragged it to the bottom of the screen.
I don't know how I lost it, but it's wonderful to know how to put it back.
several weeks ago a new lock screen appeared - out of nowhere - and now won't go away. I've tried to manually go into setting and change it - no luck. When I restart my s5, my original screen (which is still selected in settings) comes up, but is then taken over by this lock screen that won't go away. I'm running Themer - thought it was associated with that, but I've since cleared cache/data/deleted it, with no luck. This thing doesn't keep time, give any notifications, or swipe responsively. A real PIA. It also affects the notification bar - won't give me my notifications. Same with the lock screen - occasionally I will swipe my screen and see the original notification bar, but mostly this new one. Any thoughts? I'm really not keen on wiping the whole thing are starting from scratch.
A screenshot would be helpful, it sounds like part of another app you have installed.
I'm not sure what happened but all of a sudden interactive buttons no longer work as no matter where I touch the screen the app list is launched. In the past interactive buttons for calendar, fit, etc would launch the prospective functions but no longer and the app list was launched by swiping from the right of the screen. Any ideas how to get back to normal?
Which watch face?maybe it for corrupted somehow.
Try restart phone. Maybe try a different watch face.
This is a bit hard to explain. Bear with me.
On my Z300M, occasionally the screen starts flashing shortly a screen image from another app. It looks as if the app made a screenshot and that this screenshot is repeatedly shown, even though the app is no longer active.
For example, I've been looking to a television program using the (dutch) NPO Start app. I terminate the app and go to the home screen. Suddenly
a screenshot from the NPO app is shown, disappears after a second, reappears after a short while (10-20 seconds) etc. When the screenshot is shown the display is still sensitive to the buttons and icons of the home screen so it is clearly a video problem.
Only a reboot solves it.
Anyone any ideas what could be going on?
