How do you get the display width and height?

ie in java Display.getWidth()

[slant · Accepted solution]

For anyone needing to do this here's how I did it

	screen_context_t m_screen_cxt;
	int count = 0, size[2];
	screen_display_t *displays;

	screen_create_context(&m_screen_cxt, SCREEN_APPLICATION_CONTEXT);
	screen_get_context_property_iv(m_screen_cxt, SCREEN_PROPERTY_DISPLAY_COUNT, &count);

	displays = (screen_display_t*)calloc(count, sizeof(screen_display_t));

	screen_get_context_property_pv(m_screen_cxt, SCREEN_PROPERTY_DISPLAYS, (void **)displays);
	screen_get_display_property_iv(displays[0], SCREEN_PROPERTY_SIZE, size);

	free(displays);

 size[0] contains screen width, size[1] contains screen height

Try:

bb::device:: DisplayManager displayManager;
bb::device:: Display& display = displayManager.getDisplay(displayManager.primaryDisplayId());
QSize size = display.pixelSize();

I can't find DisplayManager in beta 2 :-(

If I use:

bb::device::Display display;

then I get:

C:\BB_DEV\Native\Workspaces\BB10_WS\myTazks\arm/../src/app.cpp:6: undefined reference to `bb::device::Display::Display(QObject*)' 

C:\BB_DEV\Native\Workspaces\BB10_WS\myTazks\arm/../src/app.cpp:25: undefined reference to `bb::device::Display::~Display()'

Solution:
in .pro file add LIBS += -lbbdevice

    DisplayInfo display;
    m_nScreenWidth = display.pixelSize().width();
    m_nScreenHeight = display.pixelSize().height();
