◆ SwapchainStatus

Enumerator
SwapchainAcquired 

We already called VulkanWindow::acquireNextSwapchain.

        Can only go into this state if we're coming from SwapchainReleased 
SwapchainUsedInRendering 

We already called VulkanWindow::getImageAcquiredSemaphore.

Further calls to getImageAcquiredSemaphore will return null. Ogre is rendering or intends to into this swapchain.

Can only go into this state if we're coming from SwapchainAcquired

SwapchainPendingSwap 

We've come from SwapchainUsedInRendering and are waiting for VulkanDevice::commitAndNextCommandBuffer to present us.

SwapchainReleased 

We don't own a swapchain.

Ogre cannot render to this window.

        This status should not last long unless we're not initialized yet.

Many windowing systems that support HiDPI displays use special points to specify size of the windows and controls, so that windows and controls with hardcoded sizes does not become too small on HiDPI displays.

Such points have constant density ~ 100 points per inch (probably 96 on Windows and 72 on Mac), that is independent of pixel density of real display, and are used through the all windowing system.

Sometimes, such view points are choosen bigger for output devices that are viewed from larger distances, like 30" TV comparing to 30" monitor, therefore maintaining constant points angular density rather than constant linear density.

In any case, all such windowing system provides the way to convert such view points to pixels, be it DisplayProperties::LogicalDpi on WinRT or backingScaleFactor on MacOSX. We use pixels consistently through the Ogre, but window/view management functions takes view points for convenience, as does the rest of windowing system. Such parameters are named using xxxxPt pattern, and should not be mixed with pixels without being converted using getViewPointToPixelScale() function.

Sometimes such scale factor can change on-the-fly, for example if window is dragged to monitor with different DPI. In such situation, window size in view points is usually preserved by windowing system, and Ogre should adjust pixel size of RenderWindow.

Reimplemented in Ogre::CocoaWindow, and Ogre::MetalWindow.

bool  borderless,
uint32  monitorIdx,
uint32  widthPt,
uint32  heightPt,
uint32  frequencyNumerator,
uint32  frequencyDenominator 
)
virtualinherited

Requests to toggle between fullscreen and windowed mode.

Remarks
Use wantsToGoFullscreen & wantsToGoWindowed to know what you've requested. Same remarks as requestResolution apply: If we request to go fullscreen, wantsToGoFullscreen will return true. But if get word from OS saying we stay in windowed mode, wantsToGoFullscreen will start returning false.
Parameters
goFullscreenTrue to go fullscreen, false to go windowed mode.
borderlessWhether to be borderless. Only useful if goFullscreen == false;
monitorIdx
widthNew width. Leave 0 if you don't care.
heightNew height. Leave 0 if you don't care.
frequencyNumeratorNew frequency (fullscreen only). Leave 0 if you don't care.
frequencyDenominatorNew frequency (fullscreen only). Leave 0 if you don't care.

Reimplemented in Ogre::VulkanXcbWindow, Ogre::VulkanWin32Window, Ogre::GLXWindow, Ogre::NULLWindow, Ogre::Win32Window, Ogre::EglPBufferWindow, and Ogre::EGLWindow.

◆ requestResolution()

virtual void Ogre::Window::requestResolution ( uint32  widthPt,
uint32  heightPt 
)
virtualinherited

Requests a change in resolution.

Change is not immediate. Use getRequestedWidthPt & getRequestedHeightPt if you need to know what you've requested, but beware you may not get that resolution, and once we get word from the OS, getRequested{Width/Height}Pt will change again so that getWidth == getRequestedWidthPt * getViewPointToPixelScale.

Reimplemented in Ogre::VulkanXcbWindow, Ogre::VulkanWin32Window, Ogre::VulkanAndroidWindow, Ogre::GLXWindow, Ogre::NULLWindow, Ogre::MetalWindow, Ogre::Win32Window, Ogre::EglPBufferWindow, and Ogre::EGLWindow.

virtualinherited

◆ setFocused()

virtual void Ogre::Window::setFocused ( bool  focused)
virtualinherited

◆ setFsaa()

virtual void Ogre::Window::setFsaa ( const String fsaa)
inlinevirtualinherited

Set the FSAA mode to be used if hardware support it.

This option will be ignored if the hardware does not support it or setting can not be changed on the fly on per-target level.

Parameters
fsaaRequesed FSAA mode (
See also
Root::createRenderWindow)

Reimplemented in Ogre::D3D11WindowSwapChainBased.

◆ setHidden()

virtual void Ogre::Window::setHidden ( bool  hidden)
pure virtualinherited

Hide (or show) the window.

If called with hidden=true, this will make the window completely invisible to the user.

Remarks
Setting a window to hidden is useful to create a dummy primary RenderWindow hidden from the user so that you can create and recreate your actual RenderWindows without having to recreate all your resources.

Implemented in Ogre::VulkanXcbWindow, Ogre::VulkanWin32Window, Ogre::VulkanAndroidWindow, Ogre::CocoaWindow, Ogre::GLXWindow, Ogre::D3D11Window, Ogre::NULLWindow, Ogre::MetalWindow, Ogre::Win32Window, Ogre::EglPBufferWindow, and Ogre::EGLWindow.

◆ setTitle()

virtual void Ogre::Window::setTitle ( const String title)
virtualinherited

◆ setVSync()

void Ogre::VulkanWindow::setVSync ( bool  vSync,
uint32  vSyncInterval 
)
overridevirtual

Turns VSync on/off.

Parameters
vSync
vSyncIntervalWhen true, specifies how often the screen should be updated. e.g. at 60hz: vSyncInterval = 1 then update at 60hz vSyncInterval = 2 then update at 30hz vSyncInterval = 3 then update at 15hz vSyncInterval = 4 then update at 7.5hz

If the 31st bit is set, i.e. 0x80000000, then lowest latency mode, aka mailbox, will be used (which doesn't limit the framerate)

Reimplemented from Ogre::Window.

◆ swapBuffers()

void Ogre::VulkanWindow::swapBuffers ( )
overridevirtual

Tells our VulkanDevice that the next commitAndNextCommandBuffer call should present us Calling swapBuffers during the command buffer that is rendering to us is key for good performance; otherwise Ogre may split the commands that render to this window and the command that presents this window into two queue submissions.

Implements Ogre::Window.

◆ wantsToGoFullscreen()

bool Ogre::Window::wantsToGoFullscreen ( ) const
inherited

Returns true if we are in windowed mode right now, but want to go fullscreen.

◆ wantsToGoWindowed()

bool Ogre::Window::wantsToGoWindowed ( ) const
inherited

Returns true if we are in fullscreen mode right now, but want to go windowed mode.

◆ windowMovedOrResized()

virtual void Ogre::Window::windowMovedOrResized ( )
inlinevirtualinherited

Notify that the window has been resized.

Remarks
You don't need to call this unless you created the window externally.

Reimplemented in Ogre::VulkanXcbWindow, Ogre::VulkanWin32Window, Ogre::VulkanAndroidWindow, Ogre::CocoaWindow, Ogre::GLXWindow, Ogre::MetalWindow, Ogre::Win32Window, and Ogre::EGLWindow.
