Detailed Description

The CustomTableWidget class is a subclass of QTableWidget that provides additional functionality and customization for table widgets.

Constructor & Destructor Documentation

CustomTableWidget()

CustomTableWidget::CustomTableWidget

(

QWidget *

parent = nullptr

)

Constructs a CustomTableWidget object.

Parameters

parent

The parent widget.

Member Function Documentation

cannotDeleteRow

void CustomTableWidget::cannotDeleteRow ( )

signal

Signal emitted when row deletion is not allowed.

This signal indicates that a row cannot be deleted.

generateUniqueID()

int CustomTableWidget::generateUniqueID

(

)

Generates a unique ID.

This method can be used to generate unique identifiers for table entries.

Returns

The generated unique ID.

hasEmptyCell()

bool CustomTableWidget::hasEmptyCell

(

const QList< int > &

exceptionColumns = QList<int>()

)

Checks if the table has any empty cells.

Parameters

exceptionColumns

The columns to exclude from the check.

Returns

True if there is at least one empty cell, false otherwise.

isRowEmpty()

bool CustomTableWidget::isRowEmpty	(	int	row,
		const QList< int > &	exceptionColumns = QList<int>()
	)

Checks if a row is empty.

Parameters

row	The row index.
exceptionColumns	The columns to exclude from the check.

Returns

True if the row is empty, false otherwise.

isTableIncomplete()

bool CustomTableWidget::isTableIncomplete

(

const QList< int > &

exceptionColumns = QList<int>()

)

Checks if the table is incomplete, i.e., if it does not have at least one complete row of data.

A row is considered complete if all cells in the row have non-empty data.

Parameters

exceptionColumns

(optional) A list of column indices to exclude from the completeness check. Any rows that only have empty cells in the specified columns will still be considered incomplete. Defaults to an empty list, which means all columns will be considered for completeness.

Returns

true if the table is incomplete, i.e., it does not have at least one complete row of data. false if the table has at least one complete row.

keyPress

void CustomTableWidget::keyPress ( QKeyEvent *  event )

signal

Signal emitted when a key press event occurs in the table.

Parameters

event

The key event.

keyPressEvent()

void CustomTableWidget::keyPressEvent ( QKeyEvent *  event )

overrideprotected

Overridden keyPressEvent() method to handle key press events in the table.

Parameters

event

The key event.

setCheckboxDelegateForColumns()

void CustomTableWidget::setCheckboxDelegateForColumns	(	int	row,
		const QList< int > &	columns
	)

Sets a checkbox delegate for the specified columns in a row.

Parameters

row	The row index.
columns	The columns to set the checkbox delegate for.

setData()

void CustomTableWidget::setData ( const QModelIndex &  index, const QVariant &  value, int  role = Qt::EditRole  )

protected

Overridden setData() method for custom handling of data changes in the table.

Parameters

index	The model index of the item.
value	The new value for the item.
