Method Detail

isResizable

public boolean isResizable()

Returns the resizable setting.

Returns:

boolean

setResizable

public void setResizable(boolean newResizable)

Sets whether the ResizableTextField should adjust its font size according to the size of the component.

Parameters:

newResizable - boolean

setEnhanced

public void setEnhanced(boolean newEnhanced)

Sets the enhanced mode setting. When true, the text field is painted with anti-aliasing rendering hints.

Parameters:

newEnhanced -

isEnhanced

public boolean isEnhanced()

Returns the enhanced mode setting.

Returns:

boolean

setMargin

public void setMargin(java.awt.Insets margin)

Overrides:

setMargin in class javax.swing.text.JTextComponent

Parameters:

margin - Insets

See Also:

JTextComponent.setMargin(java.awt.Insets)

setText

public void setText(java.lang.String text)

This method was overloaded to implement font resizing.

Overrides:

setText in class javax.swing.text.JTextComponent

Parameters:

text - String

See Also:

JTextComponent.setText(String)

resize

protected void resize()

Adjusts the size of the font to the size of the text field. It is safe to call this method without checking if field is in fact resizable.
