Parameters:
x - pointer x coordinate
Parameters:
y - pointer y coordinate the character index |
| getInputModeAnchor | | protected int[] getInputModeAnchor()(Code) | | This is a utility function to calculate the anchor point
for the InputModeIndicator layer. Override TextFieldLFImpl
version for effeciency.
anchor (x, y, w, h) |
| lCallShowNotify | | void lCallShowNotify()(Code) | | Called by the system to notify this Item it is being shown
The default implementation of this method updates
the 'visible' state
|
| lDelete | | public void lDelete(int offset, int length)(Code) | | Notifies L&amsp;F of character deletion in the corresponding
TextField.
Parameters:
offset - the beginning of the deleted region
Parameters:
length - the number of characters deleted
exception:
IllegalArgumentException - if the resulting contentswould be illegal for the current
exception:
StringIndexOutOfBoundsException - if offsetand length do notspecify a valid range within the contents of the TextField |
| lGetContentSize | | void lGetContentSize(int size, int availableWidth)(Code) | | Sets the content size in the passed in array.
Content is calculated based on the availableWidth.
size[WIDTH] and size[HEIGHT] should be set by this method.
Parameters:
size - The array that holds Item content size and location in Item internal bounds coordinate system.
Parameters:
availableWidth - The width available for this Item |
| lInsert | | public void lInsert(char data, int offset, int length, int position)(Code) | | Notifies L&s;F of a character insertion in the corresponding
TextBox.
Parameters:
data - the source of the character data
Parameters:
offset - the beginning of the region of characters copied
Parameters:
length - the number of characters copied
Parameters:
position - the position at which insertion occurred |
| lPaintContent | | void lPaintContent(Graphics g, int width, int height)(Code) | | Paints the content area of this TextField.
Graphics is translated to contents origin.
Parameters:
g - The graphics where Item content should be painted
Parameters:
width - The width available for the Item's content
Parameters:
height - The height available for the Item's content |
| lSetChars | | public void lSetChars()(Code) | | Notifies L&F of a content change in the corresponding TextBox.
|
| lSetConstraints | | public void lSetConstraints()(Code) | | Notifies L&s;F that constraints have to be changed.
|
| lSetMaxSize | | public void lSetMaxSize(int maxSize)(Code) | | Notifies L&s;F of a maximum size change in the corresponding
TextBox.
Parameters:
maxSize - - the new maximum size |
| moveCursor | | boolean moveCursor(int dir)(Code) | | Move the text cursor in the given direction
Parameters:
dir - direction to move true if the cursor was moved, false otherwise |
| paint | | public void paint(Graphics g, DynamicCharacterArray dca, char opChar, int constraints, Font font, int fgColor, int w, int h, int offset, int options, TextCursor cursor, TextInfo info)(Code) | | Paint the text, linewrapping when necessary
Parameters:
g - the Graphics to use to paint with. If g is null thenonly the first four arguments are used and nothing ispainted. Use this to return just the displayed string
Parameters:
dca - the text to paint
Parameters:
opChar - if opChar > 0 then an optional character to paint.
Parameters:
constraints - text constraints
Parameters:
font - the font to use to paint the text
Parameters:
fgColor - foreground color
Parameters:
w - the available width for the text
Parameters:
h - the available height for the text
Parameters:
offset - the first line pixel offset
Parameters:
options - any of Text.[NORMAL | INVERT | HYPERLINK | TRUNCATE]
Parameters:
cursor - text cursor object to use to draw vertical bar
Parameters:
info - TextInfo structure to use for paint |
| setCaretPosition | | protected void setCaretPosition(int pos)(Code) | | Set new cursor position. Update text info if cursor position is changed
Parameters:
pos - new position |
| setVerticalScroll | | boolean setVerticalScroll()(Code) | | Used internally to set the vertical scroll position
|
| uScrollAt | | protected void uScrollAt(int position)(Code) | | Perform a scrolling at the given position.
Parameters:
context - position |
| uScrollByLine | | protected void uScrollByLine(int dir)(Code) | | Perform a line scrolling in the given direction. This method will
attempt to scroll the view to show next/previous line.
Parameters:
dir - the direction of the flip, either DOWN or UP |
| uScrollViewport | | protected void uScrollViewport(int dir)(Code) | | Perform a page flip in the given direction. This method will
attempt to scroll the view to show as much of the next page
as possible. It uses the locations and bounds of the items on
the page to best determine a new location - taking into account
items which may lie on page boundaries as well as items which
may span several pages.
Parameters:
dir - the direction of the flip, either DOWN or UP |
