Constructor Detail

ProgressBar

public ProgressBar(Composite parent,
                   int style)

Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

Method Detail

checkStyle

static int checkStyle(int style)

---

createHandle

void createHandle(int index)

Overrides:

createHandle in class Widget

---

getMaximum

public int getMaximum()

Returns the maximum value which the receiver will allow.

---

getMinimum

public int getMinimum()

Returns the minimum value which the receiver will allow.

---

getSelection

public int getSelection()

Returns the single selection that is the receiver's position.

---

gtk_realize

long gtk_realize(long widget)

Overrides:

gtk_realize in class Control

---

releaseWidget

void releaseWidget()

Overrides:

releaseWidget in class Control

---

setMaximum

public void setMaximum(int value)

Sets the maximum value that the receiver will allow. This new value will be ignored if it is not greater than the receiver's current minimum value. If the new maximum is applied then the receiver's selection value will be adjusted if necessary to fall within its new range.

---

setMinimum

public void setMinimum(int value)

Sets the minimum value that the receiver will allow. This new value will be ignored if it is negative or is not less than the receiver's current maximum value. If the new minimum is applied then the receiver's selection value will be adjusted if necessary to fall within its new range.

---

setSelection

public void setSelection(int value)

Sets the single selection that is the receiver's position to the argument which must be greater than or equal to zero.

---

timerProc

long timerProc(long widget)

Overrides:

timerProc in class Widget

---

updateBar

void updateBar(int selection,
               int minimum,
               int maximum)
