Detailed Description

The Jimcpp device. You can create it with createDevice() or createDeviceEx().

This is the most important class of the Jimcpp Engine. You can access everything in the engine if you have a pointer to an instance of this class. There should be only one instance of this class at any time.

Member Function Documentation

◆ activateJoysticks()

virtual bool jpp::JimcppDevice::activateJoysticks ( core::array< SJoystickInfo > & joystickInfo )

pure virtual

Activate any joysticks, and generate events for them.

Jimcpp contains support for joysticks, but does not generate joystick events by default, as this would consume joystick info that 3rd party libraries might rely on. Call this method to activate joystick support in Jimcpp and to receive jpp::SJoystickEvent events.

Parameters

joystickInfo On return, this will contain an array of each joystick that was found and activated.

Returns: true if joysticks are supported on this device and JPP_COMPILE_WITH_JOYSTICK_EVENTS is defined, false if joysticks are not supported or support is compiled out.

◆ clearSystemMessages()

virtual void jpp::JimcppDevice::clearSystemMessages ( )

pure virtual

Remove messages pending in the system message loop.

This function is usually used after messages have been buffered for a longer time, for example when loading a large scene. Clearing the message loop prevents that mouse- or buttonclicks which users have pressed in the meantime will now trigger unexpected actions in the gui.
So far the following messages are cleared:
Win32: All keyboard and mouse messages
Linux: All keyboard and mouse messages
All other devices are not yet supported here.
The function is still somewhat experimental, as the kind of messages we clear is based on just a few use-cases. If you think further messages should be cleared, or some messages should not be cleared here, then please tell us.

◆ closeDevice()

virtual void jpp::JimcppDevice::closeDevice ( )

pure virtual

Notifies the device that it should close itself.

JimcppDevice::run() will always return false after closeDevice() was called.

◆ createDefaultRandomizer()

virtual IRandomizer * jpp::JimcppDevice::createDefaultRandomizer ( ) const

pure virtual

Creates a new default randomizer.

The default randomizer provides the random sequence known from previous Jimcpp versions and is the initial randomizer set on device creation.

Returns: Pointer to the default IRandomizer object.

◆ getColorFormat()

virtual video::ECOLOR_FORMAT jpp::JimcppDevice::getColorFormat ( ) const

pure virtual

Get the current color format of the window.

pure virtual

Provides access to the cursor control.

Returns: Pointer to the mouse cursor control interface.

◆ getDoubleClickTime()

virtual u32 jpp::JimcppDevice::getDoubleClickTime ( ) const

pure virtual

Get the maximal elapsed time between 2 clicks to generate double- and tripleclicks for the mouse.

When return value is 0 no double- and tripleclicks will be generated.

Returns: maximal time in milliseconds for two consecutive clicks to be recognized as double click

◆ getEventReceiver()

virtual IEventReceiver * jpp::JimcppDevice::getEventReceiver ( )

pure virtual

Provides access to the current event receiver.

Returns: Pointer to the current event receiver. Returns 0 if there is none.

pure virtual

Provides access to the message logger.

Returns: Pointer to the logger.

◆ getOSOperator()

virtual IOSOperator * jpp::JimcppDevice::getOSOperator ( )

pure virtual

Provides access to the operation system operator object.

The OS operator provides methods for getting system specific information and doing system specific operations, such as exchanging data with the clipboard or reading the operation system version.

Returns: Pointer to the OS operator.

◆ getRandomizer()

virtual IRandomizer * jpp::JimcppDevice::getRandomizer ( ) const

pure virtual

Provides access to the engine's currently set randomizer.

Returns: Pointer to the IRandomizer object.

◆ getSceneManager()

virtual scene::ISceneManager * jpp::JimcppDevice::getSceneManager ( )

pure virtual

Provides access to the scene manager.

Returns: Pointer to the scene manager.

◆ getTimer()

virtual ITimer * jpp::JimcppDevice::getTimer ( )

pure virtual

Provides access to the engine's timer.

The system time can be retrieved by it as well as the virtual time, which also can be manipulated.

Returns: Pointer to the ITimer object.

◆ getType()

virtual E_DEVICE_TYPE jpp::JimcppDevice::getType ( ) const

pure virtual

Get the type of the device.

This allows the user to check which windowing system is currently being used.

◆ getVersion()

virtual const c8 * jpp::JimcppDevice::getVersion ( ) const

pure virtual

Get the version of the engine.

The returned string will look like this: "1.2.3" or this: "1.2".

Returns: String which contains the version.

◆ getVideoDriver()

virtual video::IVideoDriver * jpp::JimcppDevice::getVideoDriver ( )

pure virtual

Provides access to the video driver for drawing 3d and 2d geometry.

Returns: Pointer the video driver.

◆ getVideoModeList()

virtual video::IVideoModeList * jpp::JimcppDevice::getVideoModeList ( )

pure virtual

Gets a list with all video modes available.

You only need a null driver (ED_NULL) to access those video modes. So you can get the available modes before starting any other video driver.

Returns: Pointer to a list with all video modes supported by the gfx adapter.

◆ isDriverSupported()

static bool jpp::JimcppDevice::isDriverSupported ( video::E_DRIVER_TYPE driver )

inlinestatic

Check if a driver type is supported by the engine.

Even if true is returned the driver may not be available for a configuration requested when creating the device.

◆ isFullscreen()

virtual bool jpp::JimcppDevice::isFullscreen ( ) const

pure virtual

Checks if the Jimcpp window is running in fullscreen mode.

Returns: True if window is fullscreen.

◆ isWindowActive()

virtual bool jpp::JimcppDevice::isWindowActive ( ) const

pure virtual

Returns if the window is active.

If the window is inactive, nothing needs to be drawn. So if you don't want to draw anything when the window is inactive, create your drawing loop this way:

while(device->run())
{
    if (device->isWindowActive())
    {
        // draw everything here
    }
    else
        device->yield();
}

Returns: True if window is active.

◆ isWindowFocused()

virtual bool jpp::JimcppDevice::isWindowFocused ( ) const

pure virtual

Checks if the Jimcpp window has the input focus.

Returns: True if window has focus.

◆ isWindowMinimized()

virtual bool jpp::JimcppDevice::isWindowMinimized ( ) const

pure virtual

Checks if the Jimcpp window is minimized.

Returns: True if window is minimized.

◆ postEventFromUser()

virtual bool jpp::JimcppDevice::postEventFromUser ( const SEvent & event )

pure virtual

Sends a user created event to the engine.

Is is usually not necessary to use this. However, if you are using an own input library for example for doing joystick input, you can use this to post key or mouse input events to the engine. Internally, this method only delegates the events further to the scene manager and the GUI environment.

◆ run()

virtual bool jpp::JimcppDevice::run ( )

pure virtual

Runs the device.

Also increments the virtual timer by calling ITimer::tick();. You can prevent this by calling ITimer::stop(); before and ITimer::start() after calling JimcppDevice::run(). Returns false if device wants to be deleted. Use it in this way:

while(device->run())
{
    // draw everything here
}

If you want the device to do nothing if the window is inactive (recommended), use the slightly enhanced code shown at isWindowActive().

Note if you are running Jimcpp inside an external, custom created window: Calling Device->run() will cause Jimcpp to dispatch windows messages internally. If you are running Jimcpp in your own custom window, you can also simply use your own message loop using GetMessage, DispatchMessage and whatever and simply don't use this method. But note that Jimcpp will not be able to fetch user input then. See jpp::SJimcppCreationParameters::WindowId for more information and example code.

◆ setDoubleClickTime()

virtual void jpp::JimcppDevice::setDoubleClickTime ( u32 timeMs )

pure virtual

Set the maximal elapsed time between 2 clicks to generate doubleclicks for the mouse. It also affects tripleclick behavior.

When set to 0 no double- and tripleclicks will be generated.

Parameters

timeMs maximal time in milliseconds for two consecutive clicks to be recognized as double click

◆ setEventReceiver()

virtual void jpp::JimcppDevice::setEventReceiver ( IEventReceiver * receiver )

pure virtual

Sets a new user event receiver which will receive events from the engine.

Return true in IEventReceiver::OnEvent to prevent the event from continuing along the chain of event receivers. The path that an event takes through the system depends on its type. See jpp::EEVENT_TYPE for details.

Parameters

receiver New receiver to be used.

◆ setInputReceivingSceneManager()

virtual void jpp::JimcppDevice::setInputReceivingSceneManager ( scene::ISceneManager * sceneManager )

pure virtual

Sets the input receiving scene manager.

If set to null, the main scene manager (returned by GetSceneManager()) will receive the input

Parameters

sceneManager New scene manager to be used.

◆ setRandomizer()

virtual void jpp::JimcppDevice::setRandomizer ( IRandomizer * r )

pure virtual

Sets a new randomizer.

Parameters

r	Pointer to the new IRandomizer object. This object is grab()'ed by the engine and will be released upon the next setRandomizer call or upon device destruction.

◆ setResizable()

virtual void jpp::JimcppDevice::setResizable ( bool resize = false )

pure virtual

Sets if the window should be resizable in windowed mode.

The default is false. This method only works in windowed mode.

Parameters

resize Flag whether the window should be resizable.

◆ setWindowCaption()

virtual void jpp::JimcppDevice::setWindowCaption ( const wchar_t * text )

pure virtual

Sets the caption of the window.

Parameters

text	New text of the window caption.

◆ setWindowSize()

virtual void jpp::JimcppDevice::setWindowSize ( const jpp::core::dimension2d< u32 > & size )

pure virtual

Resize the render window.

This will only work in windowed mode and is not yet supported on all systems. It does set the drawing/clientDC size of the window, the window decorations are added to that. You get the current window size with IVideoDriver::getScreenSize() (might be unified in future)

◆ sleep()

virtual void jpp::JimcppDevice::sleep	(	u32	timeMs,
		bool	pauseTimer = `false`
	)

pure virtual

Pause execution and let other processes to run for a specified amount of time.

It may not wait the full given time, as sleep may be interrupted

Parameters

timeMs	Time to sleep for in milliseconds.
pauseTimer	If true, pauses the device timer while sleeping

◆ yield()

virtual void jpp::JimcppDevice::yield ( )

pure virtual

Cause the device to temporarily pause execution and let other processes run.

This should bring down processor usage without major performance loss for Jimcpp
