public GDETextArea(GDECanvas canvas)

Constructs a new instance of GDETextArea.

Method Detail

changeCase

public void changeCase()

Changes the case of the currently selected sequence (if the sequence is of inconsistent case, the case of the entire sequence is changed to the opposite case of the first character in the sequence.

Specified by:

changeCase in interface GDECanvasObject

cut

public void cut()

Cuts content from the current Editable object.

Specified by:

cut in interface GDECanvasObject

Overrides:

cut in class BLTextArea

paste

public void paste()

Pastes content into the current Editable object.

Specified by:

paste in interface GDECanvasObject

Overrides:

paste in class BLTextArea

pdeleteSelection

public boolean pdeleteSelection()

Used to delete the current selection before an insertion or as part of a deletion. NOTE: ng stands for non-grouped

Returns:

whether or not the deletion was performed.

isSelectedLine

public boolean isSelectedLine(int y)

This function is used to test if a line is selected.

Overrides:

isSelectedLine in class BLTextArea

Parameters:

y - the Y co-ordinate (or line number) to test.

Returns:

true if the line is within the selection area, and should be printed as such.

isProtectionsOn

public boolean isProtectionsOn(Cell seq,
                               java.lang.String text)

Checks a string against all of a sequence's protection settings. This is done by obtaining the sequence's protection settings, the type of the sequence, and whether the text contains a character in any protected character class.

Parameters:

seq - the sequence to test against.

text - the text to test.

Returns:

true if the text violates the protection settings of the sequence.

getProtectAlignment

public boolean getProtectAlignment(Cell seq,
                                   java.lang.String text)

Checks a string against a sequence's alignment gap protection settings. This is done by obtaining the sequence's alignment gap protection settings, the type of the sequence, and whether the text contains a character in the alignment gap character class.

Parameters:

seq - the sequence to test against.

text - the text to test.

Returns:

true if the text violates the protection settings of the sequence.

getProtectAmbiguous

public boolean getProtectAmbiguous(Cell seq,
                                   java.lang.String text)

Checks a string against a sequence's ambiguous character protection settings. This is done by obtaining the sequence's ambiguous character protection settings, the type of the sequence, and whether the text contains a character in the ambiguous character class.

Parameters:

seq - the sequence to test against.

text - the text to test.

Returns:

true if the text violates the protection settings of the sequence.

getProtectUnambiguous

public boolean getProtectUnambiguous(Cell seq,
                                     java.lang.String text)

Checks a string against a sequence's unambiguous character protection settings. This is done by obtaining the sequence's unambiguous character protection settings, the type of the sequence, and whether the text contains a character in the unambiguous character class.

Parameters:

seq - the sequence to test against.

text - the text to test.

Returns:

true if the text violates the protection settings of the sequence.

Inserts a string into the textarea's underlying SeqDoc (NOTE: this should ONLY be called by sub-methods)

Overrides:

insert in class BLTextArea

Parameters:

x - the X co-ordinate (column number) to insert the character at.

y - the Y co-ordinate (row number) to insert the character at.

text - the text to insert.

Returns:
