Author: 2012-07-23 Steven Lambright

History:

2012-07-23 Steven Lambright - Added/fixed documentation, improved implementation of addToHistory to look for alternative text/not display blank items.

2012-07-23 Steven Lambright and Stuart Sides - Added display of undo stack

2012-07-27 Kimberly Oyama and Steven Lambright - Added resizeEvent() and improved implementation of refit().

2012-07-31 Kimberly Oyama - Added comments to some of the methods.

2017-02-06 Tracie Sucharski - Work orders that are not on the QUndoStack are greyed out and italicized.

2017-04-05 Tracie Sucharski - For the last change, method name was changed from onUndoStack to isUndoable.

2017-07-24 Cole Neubauer - Added check in addToHistory() to check if a WorkOrder should be added to the HistoryTree Fixes #4715

2017-08-10 Tyler Wilson - Changed some code in addToHistory function which was causing a segfault. This is a bandaid fix which addresses the immediate problem, but will have to be tackled in a future ticket. Fixes #5096. References #4492.

2017-08-11 Cole Neubauer - Added some checks to avoid segfaults Fixes #5064

2017-11-08 Tyler Wilson - Reverted the code change in #5096 to restore the ProgressBar, and changed code in OpenRecentProjectsWorkOrder.cpp to prevent the segfault which #5096 was addressing. Fixes #5149.

2018-04-07 Tracie Sucharski - Added method to force a history entry using a string rather than a WorkOrder. This should be a temporary method until saving a control is turned into a WorkOrder. This was done for the alpha release simply to notify the user that the control was saved. However, this history entry is not saved/restored to a project.

2018-06-28 Makayla Shepherd - Restored the ProgressBar. Fixes #5228.

Construct a history tree widget.

Parameters

project	The project to show history for
parent	The Qt-relationship parent

References addToHistory(), handleUndoIndexChanged(), refit(), showHistory(), and Isis::Project::undoStack().

◆ ~HistoryTreeWidget()

Member Function Documentation

◆ addToHistory() [1/2]

void Isis::HistoryTreeWidget::addToHistory ( QString historyEntry )

Add a non-workorder history to the display.

Parameters

(QString) historyEntry The string displayed in the history tree

References refit().

Referenced by HistoryTreeWidget(), and showHistory().

◆ addToHistory [2/2]

void Isis::HistoryTreeWidget::addToHistory ( WorkOrder * workOrder )

privateslot

Add a single work order to the display.

This uses the QUndoCommand text (if it's blank, it uses the QAction text). If there is no text, this does nothing.

Parameters

workOrder The work order to display the history for

◆ handleUndoIndexChanged

void Isis::HistoryTreeWidget::handleUndoIndexChanged ( int newIndex )

privateslot

The project's undo stack has changed.

Display the changed states appropriately.

◆ markNotUndone

void Isis::HistoryTreeWidget::markNotUndone ( QTreeWidgetItem * treeItem )

privateslot

Display the item as not an item that has been undone - it's working or done.

This colors it black and sets the text to completed (only visible if there is no progress bar).

Parameters

treeItem The given GUI tree item/row to color appropriately.

◆ markUndone

void Isis::HistoryTreeWidget::markUndone ( QTreeWidgetItem * treeItem )

privateslot

Display the item as an item that has been undone.

This colors it gray and sets the text to Undone.

Parameters

treeItem The given GUI tree item/row to color appropriately.

◆ refit()

void Isis::HistoryTreeWidget::refit ( )

This resizes the columns to an okay width for viewing all of the data cleanly.

This method depends on sizeHintForColumn() for good column sizes.

void Isis::HistoryTreeWidget::showHistory ( )

This resets the tree widget and re-initializes.

◆ sizeHintForColumn()

int Isis::HistoryTreeWidget::sizeHintForColumn ( int column ) const

protected

Get the preferred size of a given column.

This is used by resizeColumnToContents().

The work order name column prefers space not taken by other columns. The progress column prefers 200. The date column prefers a little more than the text size of a date.

Returns: The preferred width of the given column

◆ undoCommandToTreeItem

QTreeWidgetItem * Isis::HistoryTreeWidget::undoCommandToTreeItem ( const QUndoCommand * undoCommand )

privateslot

Get the QTreeWidgetItem associated with the given undo command (work order).

Returns NULL if none found or given NULL.

Parameters

undoCommand A work order

Returns: The QTreeWidgetItem that represents (is associated with) the undoCommand

◆ updateProgressWidgets

void Isis::HistoryTreeWidget::updateProgressWidgets ( )

privateslot

We need to manually manage these progress widgets because QTreeWidget does a poor job of it.

This should be called when the progress bar instances have changed (new progress, lost a progress, etc...). This is not necessary when the progress values have changed.

Failing to call this method results in seg faults when other events occur - such as a resize event.
