Detailed Description

Helper window to allow Open GL context sharing between Qt widgets and windows created by Equalizer.

This window is not intended to be used for any actual work except for being able to provide a share OpenGLContext to WindowSystem::createWindow through the WindowSettings.

Member Function Documentation

void eq::qt::ShareContextWindow::bindDrawFrameBuffer ( ) const
inlinefinalvirtual

Bind the window's draw FBO, used for multisampling.

Version
1.9

Implements eq::SystemWindow.

Definition at line 59 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::bindFrameBuffer ( ) const
inlinefinalvirtual

Bind the window's FBO, if it uses an FBO drawable.

Version
1.0

Implements eq::SystemWindow.

Definition at line 58 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::configExit ( )
inlinefinalvirtual

De-initialize this system window.

This function might be called on partially or uninitialized system windows, and the implemenation has therefore be tolerant enough to handle this case.

Version
1.0

Implements eq::SystemWindow.

Definition at line 55 of file shareContextWindow.h.

bool eq::qt::ShareContextWindow::configInit ( )
inlinefinalvirtual

Initialize this system window.

This method should take into account all attributes of the parent Window.

Returns
true if the window was correctly initialized, false on any error.
Version
1.0

Implements eq::SystemWindow.

Definition at line 54 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::doneCurrent ( ) const
inlinefinalvirtual

This results in no context being current in the current thread.

This function resets the pipe's make current cache.

Version
1.10

Implements eq::SystemWindow.

Definition at line 57 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::finish ( )
inlinefinalvirtual

Finish execution of all commands.

Version
1.5.2

Implements eq::SystemWindow.

Definition at line 63 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::flush ( )
inlinefinalvirtual

Flush all command buffers.

Version
1.5.2

Implements eq::SystemWindow.

Definition at line 62 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::joinNVSwapBarrier ( const uint32_t  group,
const uint32_t  barrier 
)
inlinefinalvirtual

Join a NV_swap_group.

See WGL or GLX implementation and OpenGL extension for details on how to implement this function.

Parameters
groupthe swap group name.
barrierthe swap barrier name.
Version
1.0

Implements eq::SystemWindow.

Definition at line 64 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::makeCurrent ( const bool  cache) const
inlinefinalvirtual

Make the system window rendering context and drawable current.

This function invalidates the pipe's make current cache.

Version
1.0

Implements eq::SystemWindow.

Definition at line 56 of file shareContextWindow.h.

bool eq::qt::ShareContextWindow::processEvent ( const Event &  event)
inlinefinalvirtual

Process an event.

Version
1.0

Reimplemented from eq::SystemWindow.

Definition at line 67 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::queryDrawableConfig ( DrawableConfig &  dc)
inlinefinalvirtual

Set up the given drawable based on the current context.

Version
1.0

Implements eq::SystemWindow.

Definition at line 66 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::swapBuffers ( )
inlinefinalvirtual

Swap the front and back buffer.

Version
1.0

Implements eq::SystemWindow.

Definition at line 61 of file shareContextWindow.h.

void eq::qt::ShareContextWindow::updateFrameBuffer ( ) const
inlinefinalvirtual

Update the window's FBO from the multisampled FBO.

Version
1.9

Implements eq::SystemWindow.

Definition at line 60 of file shareContextWindow.h.
