Member Function Documentation

int ubit::UNatDisp::chooseVisual	(	XVisualInfo &	,
		int	visual_class,
		int	depth_hint,
		bool	linear_gamma
	)

searches a visual on this UDisp.

Arguments:

• 'XVisualInfo' is initialized if the returned value is > 0
• 'visual_class' is the X visual class (typically: TrueColor or PseudoColor)
• the 'depth' argument is a hint: the visual with the closest depth available is returned
• tries to find a gamma-corrected visual if 'linear_gamma' is true (this arg is a hint, it only applies on Solaris)
• returns the depth of the visual that was found or 0 if no visual with the specified class could be found on this screen.

void ubit::UNatDisp::copySelectionCallback

(

USysEvent

)

[impl] copie reellement la selection (ou plus exactement envoie son contenu a l'appli qui la demande).

l'event doit etre un XSelectionRequestEvent

USysPixel ubit::UNatDisp::getColorPixel

(

UColorImpl &

)

returns the native color corresponding to this UColor.

Note: the color is implicitely realized if necessary

USysCursor ubit::UNatDisp::getCursor

(

const UCursor &

)

returns the native cursor corresponding to this UCursor.

the cursor is implicitely realized if necessary

UNatFont * ubit::UNatDisp::getFont

(

const UFontDesc &

)

returns the native font corresponding to this UFont.

Note: the font is implicitely realized if necessary

void ubit::UNatDisp::pasteSelectionCallback

(

USysEvent

)

[impl] recupere effectivement le contenu de la X selection.

l'appel de cette fct est provoque par pasteSelectionRequest() the XEvent must be a XSelectionEvent event.

void ubit::UNatDisp::pasteSelectionRequest

(

UEvent &

)

[impl] asks the X selection.

cette fct ne recupere PAS tout de suite le contenu de la selection mais entrainera un appel ulterieur de pasteSelectionCallback(). the UEvent must be a button event.

bool ubit::UNatDisp::realizeColor

(

UColorImpl &

)

allocates physical resources for this UColor on this display.

Returns true if the color could be allocated. returns false and sets a default color otherwise

bool ubit::UNatDisp::realizeCursor

(

const UCursor &

)

allocates physical resources for this UCursor on this display.

returns true if the cursor could be realized and false otherwise

void ubit::UNatDisp::realizeFontFamily

(

const UFontFamily &

)

Allocates physical resources for this UFont/UFontDesc on this UDisp.

returns true if the font was found and false otherwise

bool ubit::UNatDisp::setCursor	(	UNatWin &	,
		const UCursor *
	)

sets the cursor of this window.

the default cursor will used if argument is null.

bool ubit::UNatDisp::setSelectionOwner

(

UEvent &

)

[impl] tells the server we own the X selection.

the UEvent must be a button event

int ubit::UNatDisp::setVisual	(	const XVisualInfo &	,
		USysColormap	= None
	)

sets the visual of this UDisp according to the XVisualInfo argument.

Notes:

• the Colormap is automatically created if this argument is 'None'
• this function must be called before the X windows are realized

int ubit::UNatDisp::setVisual	(	int	visual_class,
		int	depth_hint,
		bool	linear_gamma,
		USysColormap	= None
	)

sets the visual of this display according to 'visual_class' and 'depth_hint'.

Arguments:

• 'visual_class' is the X visual class (typically: TrueColor or PseudoColor)
• the 'depth' argument is a hint: the visual with the closest depth available is used
• tries to find a gamma-corrected visual if 'linear_gamma' is true (this arg is a hint, it only applies on Solaris)
• the Colormap is automatically created if this argument is 'None'
• returns the depth of the visual that was found or 0 if no visual with the specified class could be found on this screen. Note:
• this function must be called before the X windows are realized

struct { ... } ubit::UNatDisp::atoms

useful X11 Atoms.

• UMS_WINDOW: a X window that has this property will receive UMS events.
• UMS_MESSAGE: the property for exchanging messages between applications. see also: umsproto.hpp and the UMS server (available in directory ubit/ums).
