Detailed Description

event conditions.

for specifying conditionnal objects and callback functions

• general usage: condition / object
• callbacks: condition / ucall(...)
• see also: ucall() template, UCall class, ucall.hh header.
• !CAUTION: NEVER delete UOn (and subclasses) instances

Member Data Documentation

UOn UOn::action [static]

high-level activation event. event received by activable boxes (eg. UButton, UCheckbox, UTextbox). Notes: Boxes can be made activable by setting their CAN_ACTION mode. This event is discarded if the box is not enabled (see: UGroup::enable())

UOn UOn::add [static]

adding and removing children. events received by the parent(s) of the objects that are being added or removed. Note: UEvent::getTarget(),getBoxTarget(),getBrickTarget() returns the child that was added or removed (which may have been destroyed in the latter case)

UOn UOn::arm [static]

arm/disarm button events. events received by armable boxes (eg. UButton, UCheckbox) when they are activated (event order is: arm / action / disarm) Notes: Boxes can be made armable by setting their CAN_ARM mode (see: UMode::canArm and UGroup::setCmodes()) these events are discarded if the box is not enabled (see: UGroup::enable())

UOn UOn::change [static]

value change. events received by UProp, UElem, UStr objects when their value is changed. Note: UEvent::getChangedProp(), getChangedElem(), getChangedStr() return the object whose value was changed

UOn UOn::close [static]

window closing. event received by windows that are being closed.

UOn UOn::destruct [static]

object destruction. event received by objects that are being destructed.

UOn UOn::disarm [static]

arm/disarm button events. events received by armable boxes (eg. UButton, UCheckbox) when they are activated (event order is: arm / action / disarm) Notes: Boxes can be made armable by setting their CAN_ARM mode (see: UMode::canArm and UGroup::setCmodes()) these events are discarded if the box is not enabled (see: UGroup::enable())

UOn UOn::elemChange [static]

box child change. events received by boxes when the value of their UProp, UElem, UStr... children is changed. Notes: elemChange and strChange are both emitted by UStr children (in this order) UEvent::getChangedProp(), getChangedElem(), getChangedStr() return the object whose value was changed

UOn UOn::enter [static]

UOn UOn::idle [static]

no action event. used for style specs.

UOn UOn::kpress [static]

key events. Notes: kpress and krelease are produced by raw key events ktype is a higher-level event that compose ASCII characters it is not activated by special or function keys (eg. LEFT, F1...)

UOn UOn::krelease [static]

key events. Notes: kpress and krelease are produced by raw key events ktype is a higher-level event that compose ASCII characters it is not activated by special or function keys (eg. LEFT, F1...)

UOn UOn::leave [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mbiclick [static]

mouse clicks. mclick is received when a mouse click is performed on a box, mbiclick when a double click is performed, etc. Notes: a double click first produces a mclick then a mbiclick (and so on for other multiple click events) mouse clicks are not emitted if the mouse has been moved more that a certain radius between the mouse press and release UOn::action is received after the mouse clicks

UOn UOn::mclick [static]

mouse clicks. mclick is received when a mouse click is performed on a box, mbiclick when a double click is performed, etc. Notes: a double click first produces a mclick then a mbiclick (and so on for other multiple click events) mouse clicks are not emitted if the mouse has been moved more that a certain radius between the mouse press and release UOn::action is received after the mouse clicks

UOn UOn::mdrag [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mmove [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mpress [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mquadclick [static]

mouse clicks. mclick is received when a mouse click is performed on a box, mbiclick when a double click is performed, etc. Notes: a double click first produces a mclick then a mbiclick (and so on for other multiple click events) mouse clicks are not emitted if the mouse has been moved more that a certain radius between the mouse press and release UOn::action is received after the mouse clicks

UOn UOn::mrelax [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mrelease [static]

mouse events. Details: mmove is received by the box where the mouse is currently located mdrag and mrelease are received by the box that got the mpress mrelax is similar to mrelease but it is received by the box where the mouse was released (instead of the box that got mpress)

UOn UOn::mtriclick [static]

mouse clicks. mclick is received when a mouse click is performed on a box, mbiclick when a double click is performed, etc. Notes: a double click first produces a mclick then a mbiclick (and so on for other multiple click events) mouse clicks are not emitted if the mouse has been moved more that a certain radius between the mouse press and release UOn::action is received after the mouse clicks

UOn UOn::notifyEvent [static]

application and hard window events. umessage : ubit message sent by another Ubit appli notify : notification events sent by the windowing system rawEvent : any X event (received before other events)

UOn UOn::preChildEvent [static]

detects events that *will* be received by children. intercepts events that will be received by the direct or indirect children of an UBox (or subclass): the corresponding callbacks are called while traversing the instance graph (*before* the children are reached) children will then receive events as usual all UEvent methods (such as getSource(), getX(), getY() ...) are relative to the parent (as the Event has not yet reached the destination child it can't be identified at this stage) note that many event conditions are meaningless at this stage (for instance, UOn:select is meaningless as the child has not yet be reached) this mechanism can be used to modify events dynamically (it is for instance used for transparent tools) this will only work with UBox(es) and subclasses : an UGroup can't intercept the Events that are sent to its children See also: UBox::onPostChildEvent() which makes it possible to detect events that have already been received by children. Note: another way to detect events thst would be sent to children is to use transparent glasses (all Ubit gadgets can be transparent) This technique makes it also possible to draw on the top of other objects.

UOn UOn::propChange [static]

box child change. events received by boxes when the value of their UProp, UElem, UStr... children is changed. Notes: elemChange and strChange are both emitted by UStr children (in this order) UEvent::getChangedProp(), getChangedElem(), getChangedStr() return the object whose value was changed

UOn UOn::rawEvent [static]

application and hard window events. umessage : ubit message sent by another Ubit appli notify : notification events sent by the windowing system rawEvent : any X event (received before other events)

UOn UOn::remove [static]

adding and removing children. events received by the parent(s) of the objects that are being added or removed. Note: UEvent::getTarget(),getBoxTarget(),getBrickTarget() returns the child that was added or removed (which may have been destroyed in the latter case)

UOn UOn::select [static]

item selection. events received by selectable boxes (eg. UCheckbox) when they are selected (resp. unselected) or by listboxes when one of their item is selected (resp. unselected) Notes: UEvent::getTarget(), getBoxTarget() return the listbox item that was selected or unselected any box can be made selectable by setting its CAN_SELECT mode (see: UMode::canSelect and UGroup::setCmodes())

UOn UOn::strChange [static]

box child change. events received by boxes when the value of their UProp, UElem, UStr... children is changed. Notes: elemChange and strChange are both emitted by UStr children (in this order) UEvent::getChangedProp(), getChangedElem(), getChangedStr() return the object whose value was changed

UOn UOn::umessage [static]

application and hard window events. umessage : ubit message sent by another Ubit appli notify : notification events sent by the windowing system rawEvent : any X event (received before other events)

UOn UOn::unselect [static]

item selection. events received by selectable boxes (eg. UCheckbox) when they are selected (resp. unselected) or by listboxes when one of their item is selected (resp. unselected) Notes: UEvent::getTarget(), getBoxTarget() return the listbox item that was selected or unselected any box can be made selectable by setting its CAN_SELECT mode (see: UMode::canSelect and UGroup::setCmodes())

UOn UOn::viewMove [static]

View events. These events are related to object' *views* (and thus, may be produced several times for a single Box object if this object has several parents)

UOn UOn::viewPaint [static]

View events. These events are related to object' *views* (and thus, may be produced several times for a single Box object if this object has several parents)

UOn UOn::viewResize [static]

View events. These events are related to object' *views* (and thus, may be produced several times for a single Box object if this object has several parents)
