		GridBagConstraints	gbc,
		String	labelText,
		String	tooltipText,
		JComponent	component )

Adds a labeled row to a panel using GridBagLayout.

The row consists of a JLabel on the left and the specified JComponent on the right. Optionally, a tooltip can be set for the label.

Parameters

panel	the `JPanel` to which the row is added; must not be null
gbc	the `GridBagConstraints` used for layout positioning; must not be null
labelText	the text for the `JLabel`; must not be null
tooltipText	the tooltip text for the label; may be null or blank
component	the `JComponent` to add next to the label; must not be null

◆ assignComponentNames()

void fr.softsf.canscan.ui.UiComponentsConfiguration.assignComponentNames ( NativeImageUiComponents nativeImageUiComponents )

Assigns unique names to all GUI components encapsulated in the given NativeImageUiComponents instance.

This allows automated test frameworks, such as native image configuration simulators, to reliably identify each component by name.

Parameters

nativeImageUiComponents the NativeImageUiComponents containing the GUI elements to name; must not be null

◆ attachLimitedDocumentListener()

void fr.softsf.canscan.ui.UiComponentsConfiguration.attachLimitedDocumentListener	(	JTextField	field,
		int	maxLength,
		Runnable	action )

Attaches a DocumentListener to a JTextField that:

Executes the given action on any change to the document (insert, remove, or change), asynchronously on the Swing EDT.
Limits the text length to maxLength characters using a DocumentFilter.
Removes line breaks (
, \r) from pasted or inserted text.

This allows dynamic updates (e.g., QR code preview) while preventing input overflow and unwanted line breaks.

Parameters

field	the `JTextField` to attach the listener to; must not be null
maxLength	the maximum number of characters allowed in the field
action	the `Runnable` to execute on document changes; must not be null

Here is the call graph for this function:
