public FoldIndicator(RTextArea textArea)

方法详细资料

createToolTip

public javax.swing.JToolTip createToolTip()

Overridden to use the editor's background if it's detected that the user isn't using white as the editor bg, but the system's tool tip background is yellow-ish.

覆盖:

createToolTip 在类中 javax.swing.JComponent

返回:

The tool tip.

getFoldIconBackground

public java.awt.Color getFoldIconBackground()

Returns the color to use for the "background" of fold icons. This is be ignored if custom icons are used.

返回:

The background color.

另请参阅:

setFoldIconBackground(Color)

getPreferredSize

public java.awt.Dimension getPreferredSize()

覆盖:

getPreferredSize 在类中 javax.swing.JComponent

getShowCollapsedRegionToolTips

public boolean getShowCollapsedRegionToolTips()

Returns whether tool tips are displayed showing the contents of collapsed fold regions when the mouse hovers over a +/- icon.

返回:

Whether these tool tips are displayed.

另请参阅:

setShowCollapsedRegionToolTips(boolean)

getToolTipLocation

public java.awt.Point getToolTipLocation(java.awt.event.MouseEvent e)

Positions tool tips to be aligned in the text component, so that the displayed content is shown (almost) exactly where it would be in the editor.

覆盖:

getToolTipLocation 在类中 javax.swing.JComponent

参数:

e - The mouse location.

getToolTipText

public java.lang.String getToolTipText(java.awt.event.MouseEvent e)

Overridden to show the content of a collapsed fold on mouse-overs.

覆盖:

getToolTipText 在类中 javax.swing.JComponent

参数:

e - The mouse location.

paintComponent

protected void paintComponent(java.awt.Graphics g)

覆盖:

paintComponent 在类中 javax.swing.JComponent

setFoldIconBackground

public void setFoldIconBackground(java.awt.Color bg)

Sets the color to use for the "background" of fold icons. This will be ignored if custom icons are used.

参数:

bg - The new background color.

另请参阅:

getFoldIconBackground()

setFoldIcons

public void setFoldIcons(javax.swing.Icon collapsedIcon,
                javax.swing.Icon expandedIcon)

Sets the icons to use to represent collapsed and expanded folds.

参数:

collapsedIcon - The collapsed fold icon. This cannot be null.

expandedIcon - The expanded fold icon. This cannot be null.

setShowCollapsedRegionToolTips

                                    int line,
                                    java.awt.Rectangle editorRect)

Returns the bounds of a child view as a rectangle, since Views tend to use Shape.

参数:

parent - The parent view of the child whose bounds we're getting.

line - The index of the child view.

editorRect - Returned from the text area's getVisibleEditorRect method.

返回:

The child view's bounds.
