Semester 5 Gui Final

Front 1

Some Shape simple primitives include...

Back 1

Rectangle, ellipse, line, polyline, polygon, path and ditrigonal icosideodecahedron.

Front 2

Do shapes draw themselves?

Back 2

Yes, there is no need to refresh them.

Front 3

Shapes can be placed just like other elements. What is the best container for shapes?

Back 3

Canvas.

Front 4

Some properties of shapes include...

Back 4

Fill, Stroke (Line around the shape), StrokeThickness, StrokeStartLineCap, StrokeEndLineCap and Stretch.

Front 5

Shapes can also transform allowing you to rotate and do other things with them. List some methods for transforming Shapes.

Back 5

Translate -> x, y

Rotate -> angle, centreX, centreY

Scale -> scaleX, scaleY, centreX, centreY

Skew -> angleX, angleY, centreX, centreY

Matrix -> A matrix

Front 6

Front 8

In WPF, it will route the event along the tree of elements until it finds a handler?

Back 8

True.

Front 9

If no handler is found for a event on a given element WPF will continue the event all the way to the root element to find a handler if necessary?

Back 9

True.

Front 10

Routed events can only travel in one direction?

Back 10

False. Routed events can travel in two directions, depending on how the event is defined.

Front 11

Events are said to "bubble" down when they move away from he root?

Back 11

False. Events are said to "bubble" up through the tree when they are moving toward the root element.

Front 12

Events are said "tunnel" down when they move away from the root element?

Back 12

True.

Front 13

The standard signature for an event handler is...

Back 13

void Hanlde_Event(object sender, EventArgs e)

Front 14

The standard signature for a routed event handler is the exact same as the event handler signature?

Back 14

False. The signature is almost identical except instead of EventArgs e, it's RoutedEventArgs e

Front 15

Define the Source property of RoutedEventArgs

Back 15

Source: The object that raised the event. Its useful to note that with routed events this is likely to be different from the sender.

Front 16

Define the OriginalSource property of RoutedEventArgs

Back 16

OriginalSource: This returns the original reporting source. That's the object that really raised the event.

Front 17

Define the Handled property of RoutedEventArgs

Back 17

Handled: A bool that lets you know if the event has already been handled.

Front 18

Define the RoutedEvent property of RoutedEventArgs

Back 18

RoutedEvent: This identifies the type of event that was raided.

Front 19

By adding in e.Handled = true, it tells the routed event system that we are finished with the event?

Back 19

True.

Front 20

When should you make use of Routed events?

Back 20

When you want to build your own custom controls. You can generate this by creating generic event handlers for parent elements.

Front 21

If we have a StackPanel with buttons and want a generic event handler for a button click, what tag do we need to add to the StackPanel?

Back 21

ButtonBase.Click. We could just use Button.Click, whats important is knowing the syntax.

[ Type.EventName ].

Front 22

Drag and Drop in WPF involves two containers, what are these containers called?

Back 26

The DragEnter event is used to detect a dragging over the destination control.

Front 27

The data from a drop must be in the expected format/type?

Back 27

True. If the destination control is expecting strings and you pass in raw integers it wont allow it.

Front 28

How can you check the data of a given drag event?

Back 28

GetDataPresent()

Front 29

The drop event is only fired when the user releases the mouse button?

Back 29

True.

Front 30

GetData() and GetDataPresent() are the same?

Back 30

False. GetDataPresent() is called when an item is being dragged into the destination control. GetData() is called once the drop event has triggered and the item is dropped in the destination control.

Front 31

Briefly describe the PreviewMouseleftButtonDown event

Back 31

Fires immediately before the MouseLeftButtonDown event.

Front 32

Briefly describe the MouseMove event

Back 32

Fires when mouse is moved over the control.

Back 33

Fires when the dragged item enters the control. Used to decide if the current location is a suitable drop location for the given drag item.

Front 34

Briefly describe the Drop event

Back 34

Fires when the mouse is released while dragging! Used to complete the drop by retrieving the DataObject.

Front 35

Describe the DragEnter event

Back 35

Uses DragEventArgs e. Used to control what cursor the user sees while dragging. Controlled by the control being dragged onto.

Front 36

Describe the Drop event

Back 36

Uses DragEventArgs e. Calls e.Data.GetDataPresent(). In brackets is the type you expect, if the type isnt the same it returns null.
