PlayN Fullscreen - fullscreen

I don't know why it is not working.
I want to start my game in fullscreen on desktop (Java).
Code
#Override
public void setToFullScreen() {
int screenHeight = graphics().screenHeight();
int screenWidth = graphics().screenWidth();
log().debug("ScreenHeight: " + screenHeight);
log().debug("ScreenWidth: " + screenWidth);
graphics().setSize(screenWidth, screenHeight);
}
The log says:
ScreenHeight: 480
ScreenWidth: 640
My possible resolution would be full hd - any ideas?

PlayN is not made for Java-fullscreen-mode.
The Java-Applet view is made for debugging reasons for all other platforms.
If you want to use fullscreen mode, you probably need to change the PlayN-java-sourcecode.
You maybe have to use the method
java.awt.GraphicsDevice.setFullScreenWindow(...)

The commands
graphics().screenWidth();
graphics().screehHeight();
give you the size of the playn game window.
if you want to adjust the screen size to Full HD, you have to do it like this:
graphics().setSize(1920, 1080);
this will set the size of the playn window to 1920, 1080. Howerver, this does not set your game to full screen.

Don't know which version you are using, but in the bleeding edge (1.5-SNAPSHOT) those functions return the REAL screen resolution every time.

Calculating the correct width to resize image to display in a CListCtrl

At the moment I am having to fudge my code like this:
CRect rcList;
m_ListThumbnail.GetClientRect(rcList);
rcList.DeflateRect(25, 25);
// Use monitor 1 to work out the thumbnail sizes
CRect rcMonitor = m_monitors.rcMonitors.at(0);
m_iThumbnailWidth = rcList.Width();
double dHt = ((double)rcMonitor.Height() / (double)rcMonitor.Width()) * (double)m_iThumbnailWidth;
m_iThumbnailHeight = (int)dHt;
I fudge it by deflating the rectangle by 25. m_ListThumbnail is a CListCtrl and I am trying to render my thumbnails so that I do not need a horizontal scroll bar.
When I render the thumbnails of the monitors, I attempt to massage these thumbnail values (incomplete):
nWidth = m_iThumbnailWidth;
double dHt = ((double)rcCapture.Height() / (double)rcCapture.Width()) * (double)m_iThumbnailWidth;
nHeight = (int)dHt;
if (nHeight > m_iThumbnailHeight)
{
AfxMessageBox(L"Need to investigate!");
}
Where rcCapture is the size of the monitor.
If I remove the DeflateRect line, my window displays like this:
As you can see, it is note as I expected. There is a horizontal scroll bar and I have to resize quite a bit to see the thumbnail:
All I want to compute is a set of thumbnail dimensions so that the scaled down monitor image is going to fit in the CListCtrl. I don't really want the user to have to resize the window.
Update
With my adjusted code which now uses the primary monitor aspect ratio to work out the thumbnail sizes (as added above) renders the app with better whitespace:
That was the reason of the extra space at the bottom because the monitors were 16:9 and I was squishing into 4:3. So that is fixed.
But as you can see, using the CListCtrl client width is not sufficient.
Update
This is the rendering code:
// Set the mode first!
SetStretchBltMode(dcImage, COLORONCOLOR);
int iTop = (m_iThumbnailHeight - nHeight) / 2;
// Copy (and resize)
bRet = ::StretchBlt(dcImage, 0, iTop,
nWidth,
nHeight,
dcScreen.m_hDC,
rcCapture.left,
rcCapture.top,
rcCapture.Width(),
rcCapture.Height(), SRCCOPY | CAPTUREBLT);
The control renders the icon with a margin. When I used GetItemPosition function it indicated that the x value was 21. This is why my DeflateRect(25, 25) worked. But I don;t know how the CListCtrl computed that margin value.
Eventually I found out how to do this without deflating, by using the SetIconSpacing function. Like this:
m_ListThumbnail.SetIconSpacing(
CSize(m_iThumbnailWidth, ::GetSystemMetrics(SM_CXHSCROLL)));
Once the above has been done the window looks like this:
Things might be a little different when there are 3 or 4 monitor thumbnails, thus causing a vertical scroll bar. But I only have two monitors to test with.

Different wallpaper for each monitor in a multi-monitor setup in Windows 10

There are a number of questions and answers about setting wallpapers programmatically on multi-monitor setups in Windows, but I'm asking specifically for Windows 10 (and maybe Windows 8) because it seems to work differently from all the explanations I found.
Raymond Chen has an article "How do I put a different wallpaper on each monitor?" (https://devblogs.microsoft.com/oldnewthing/?p=25003), also quoted in Monitors position on Windows wallpaper. The core concepts is that Windows places the top-left corner of the provided bitmap at the top-left corner of the primary monitor, and wraps around to fill any desktop space to the left and/or above that. I understand that, I wrote a little program using that knowledge, and it works beautifully in Windows 7.
How it works: I create a bitmap that conceptually covers the whole desktop space, as the user sees it. I draw the contents of each monitor to that bitmap in its appropriate position (the program is written in C++ using VCL, but the principle remains the same in other programming environments):
TRect GetMonitorRect_WallpaperCoords(int MonitorNum)
{
Forms::TMonitor *PrimaryMonitor = Screen->Monitors[0];
Forms::TMonitor *Monitor = Screen->Monitors[MonitorNum];
// Get the rectangle in desktop coordinates
TRect Rect(Monitor->Left, Monitor->Top, Monitor->Left + Monitor->Width, Monitor->Top + Monitor->Height);
// Convert to wallpaper coordinates
Rect.Left += PrimaryMonitor->Left - Screen->DesktopLeft;
Rect.Top += PrimaryMonitor->Top - Screen->DesktopTop;
Rect.Right += PrimaryMonitor->Left - Screen->DesktopLeft;
Rect.Bottom += PrimaryMonitor->Top - Screen->DesktopTop;
return Rect;
}
std::unique_ptr<Graphics::TBitmap> CreateWallpaperBitmap_WallpaperCoords()
{
std::unique_ptr<Graphics::TBitmap> Bmp(new Graphics::TBitmap);
Bmp->PixelFormat = pf24bit;
Bmp->Width = Screen->DesktopWidth;
Bmp->Height = Screen->DesktopHeight;
// Draw background (not that we really need it: it will never be visible)
Bmp->Canvas->Brush->Style = bsSolid;
Bmp->Canvas->Brush->Color = clBlack;
Bmp->Canvas->FillRect(TRect(0, 0, Bmp->Width, Bmp->Height));
for (int MonitorNum = 0; MonitorNum < Screen->MonitorCount; ++MonitorNum)
{
TDrawContext DC(Bmp->Canvas, GetMonitorRect_WallpaperCoords(MonitorNum));
DrawMonitor(DC);
}
return Bmp;
}
(The draw context uses a coordinate translation rect so that the code int DrawMonitor function can draw in a rectangle like (0, 0, 1920, 1080) without having to wonder where in the full bitmap it is drawing, and with a clip rect so that DrawMonitor can not accidentally draw outside of the monitor it's drawing on).
Then I convert that bitmap to an image that will properly wrap around when placed at the top-left corner of the primary monitor (as Raymond Chen describes in his article):
std::unique_ptr<Graphics::TBitmap> ConvertWallpaperToDesktopCoords(std::unique_ptr<Graphics::TBitmap> &Bmp_WallpaperCoords)
{
std::unique_ptr<Graphics::TBitmap> Bmp_DesktopCoords(new Graphics::TBitmap);
Bmp_DesktopCoords->PixelFormat = Bmp_WallpaperCoords->PixelFormat;
Bmp_DesktopCoords->Width = Bmp_WallpaperCoords->Width;
Bmp_DesktopCoords->Height = Bmp_WallpaperCoords->Height;
// Draw Bmp_WallpaperCoords to Bmp_DesktopCoords at four different places to account for all
// possible ways Windows wraps the wallpaper around the left and bottom edges of the desktop
// space
Bmp_DesktopCoords->Canvas->Draw(Screen->DesktopLeft, Screen->DesktopTop, Bmp_WallpaperCoords.get());
Bmp_DesktopCoords->Canvas->Draw(Screen->DesktopLeft + Screen->DesktopWidth, Screen->DesktopTop, Bmp_WallpaperCoords.get());
Bmp_DesktopCoords->Canvas->Draw(Screen->DesktopLeft, Screen->DesktopTop + Screen->DesktopHeight, Bmp_WallpaperCoords.get());
Bmp_DesktopCoords->Canvas->Draw(Screen->DesktopLeft + Screen->DesktopWidth, Screen->DesktopTop + Screen->DesktopHeight, Bmp_WallpaperCoords.get());
return Bmp_DesktopCoords;
}
Then I install that bitmap as a wallpaper by writing the appropriate values in the registry and calling SystemParametersInfo with SPI_SETDESKWALLPAPER:
void InstallWallpaper(const String &Fn)
{
// Install wallpaper:
// There are 3 name/data pairs that have an effect on the desktop wallpaper, all under HKCU\Control Panel\Desktop:
// - Wallpaper (REG_SZ): file path and name of wallpaper
// - WallpaperStyle (REG_SZ):
// . 0: Centered
// . 1: Tiled
// . 2: Stretched
// - TileWallpaper (REG_SZ):
// . 0: Don't tile
// . 1: Tile
// We don't use the Wallpaper value itself; instead we use SystemParametersInfo to set the wallpaper.
// The file name needs to be absolute!
assert(Ioutils::TPath::IsPathRooted(Fn));
std::unique_ptr<TRegistry> Reg(new TRegistry);
Reg->RootKey = HKEY_CURRENT_USER;
if (Reg->OpenKey(L"Control Panel\\Desktop", false))
{
Reg->WriteString(L"WallpaperStyle", L"1");
Reg->WriteString(L"TileWallpaper", L"1");
Reg->CloseKey();
}
SystemParametersInfoW(SPI_SETDESKWALLPAPER, 1, Fn.c_str(), SPIF_UPDATEINIFILE | SPIF_SENDCHANGE);
}
But when I test it in Windows 10, it doesn't work properly anymore: Windows 10 puts the wallpaper completely in the wrong place. Seeing as other people have asked questions about multi-monitor wallpapers in the past, I'm hoping there are people with experience of it on Windows 10.
As far as I can see, Windows 10 places the top-left corner of the provided bitmap at the top-left corner of the desktop space (by which I mean the bounding rectangle of all monitors), instead of the top-left corner of the primary monitor. In code, that means: I leave out the ConvertWallpaperToDesktopCoords step, and then it works fine as far as I can see.
But I can't find any documentation on this, so I don't know if this is officially explanation of how Windows 10 does it. Use with care. Also I don't know when this different behavior started: in Windows 10, or maybe earlier in Windows 8.

Move MKMapView legal label on rotation

I have an MKMapView with an iAd banner on top. Due to this iAd Banner covering the MKMapView's legal label, it is moved. The following code is performed in viewDidLayoutSubviews:
NSLog(#"ViewDidLayoutSubviews called");
UILabel *attributionLabel = [self.mapView.subviews objectAtIndex:1];
if (adBannerViewFrame.origin.y < attributionLabel.frame.origin.y) {
NSLog(#"Banner Y coordinate: %f", adBannerViewFrame.origin.y);
CGRect legalFrame = attributionLabel.frame;
legalFrame.origin.y -= IAD_BANNER_HEIGHT;
attributionLabel.frame = legalFrame;
NSLog(#"Legal y: %f", legalFrame.origin.y);
NSLog(#"Legal x: %f", legalFrame.origin.x);
NSLog(#"Legal width: %f", legalFrame.size.width);
NSLog(#"Legal height: %f", legalFrame.size.height);
}
When I switch from the View Controller containing the map to another VC and back again, the code above works perfect, regardless of orientation; however, when rotating the devices without switching VCs, the legal label disappears on rotation and don't come back until I switch back and fourth between VCs again. The NSLogs print out the exact same for both rotation and VC switching:
ViewDidLayoutSubviews called
Banner Y coordinate: 902/646(rotation dependent)
Legal x: 882/626(rotation dependent)
Legal y: 11
Legal width: 48
Legal height 11
Despite everything looking the same, the label is gone after rotating (not sure if it is moved out of the view or if it actually disappears)
The iAd Banner is reloaded in ViewDidAppear (which is called when VCs are switched back and fourth). However, since the NSLogs print the same for both scenarios, I cannot see how it should make any difference. To be sure, I tried to reload the iAd Banner in ViewDidLayoutSubviews as well, with no different result than before. Anyone experienced anything similar or know how to fix this?
For anyone encountering the same issue, I found a solution. The workaround was to schedule a timer with 0 seconds and have the timer call the method executing the code above.
[NSTimer scheduledTimerWithTimeInterval:0 target:self selector:#selector(test) userInfo:nil repeats:NO];
I assume that something was not completely finished when viewDIDlayoutSubviews was called and that adding a timer (which is not 100 % accurate and will therefore not start immediately), allowed the unknown remaining stuff to complete before the code in the question was executed.

Run 2 UIs on diffrent monitor using qt-creator on Dual-Head Graphics Card

I have a Dual-Display Graphics card, on my system (RHEL 6.3).
I have developed one simple application using qt creator (qt-4.8), which throws two different UIs.
When I execute this then both UIs starts in only one display.
What I need is my one UI should run on primary screen and one on secondary screen (i.e. 0.0 and 0.1).
How should I do this using qt-creator?
xclock -display :0.0
xclock -display :0.1
works fine.
You can use a QDesktopWidget to get screen information. It Allows you to query the amount of screens and the dimension of each one with
int QDesktopWidget::screenCount () const;
const QRect QDesktopWidget::availableGeometry ( int screen = -1 ) const;
From there, you can move your widget to any given screen. For instance, the following code move the widget to a given screen or to the default one if the specified screen is not available:
QDesktopWidget* w = QApplication::desktop();
//some value
int mydesiredscreen = 1;
//fallback to default screen if none
if(mydesiredscreen >= w->screenCount()) mydesiredscreen = -1;
QRect rect1 = w->availableGeometry(mydesiredscreen);
mywindow->move(rect1.topLeft());
Tejas,
To display your Second UI on Secondary Monitor you can use setParent property for your Second UI as :
int screenNumber = 1; /* Desired screen no */
QWidget secondaryUI_widget; /* Secondary UI Object which is to be displayed on secondary monitor */
QDesktopWidget myDesktopWidget; /* Create an object of QDesktopWidget */
secondUI_myDesktopWidget.setParent(myDesktopWidget(screenNumber));
The above line will set the desired screen on which you would like to display your page as parent for your UI object.
Now you can call show() function for your second UI anywhere in your program , the second UI will be displayed on desired screen number as being by screenNumber value

Nokia N97 realted to orientation

Myself shweta dodiya.I am facing problem with nokia N97 related to change orientation for my game application.
I am using J2me technology.I want to pause my application when i open my slider.
Thanks in advance
I don't know what code are you using, or are you using Canvas to draw the game on screen, or some other API that does that for you...
If you have something like this GameScreen extends Canvas and you use GameScreen object to draw and display the game, you need to add an override to sizeChanged method to it and check the new width (w) and the new height (h) of the GameScreen, and do the things you want in regards to that:
public void sizeChanged(int w, int h)
{
if(h > w) //NORMAL
{
drawGame();
if(paused) resumeGame();
}
else //LANDSCAPE
{
pauseGame();
drawPauseScreen();
}
}
This is a simple pseudo code, I hope you are getting the point. If statement is checking the relation between new width and the new height. If the phone is in landscape mode, H is less then W...
