Drawing tools on the diagram canvas always started new shapes and free text from a fixed hardcoded default (Qt's plain QPen()/QBrush(), and the static Preferences font) -- changing a shape's color or a text's font had zero effect on what the next new item of that type got, even within the same editing session. Add LastUsedStyle: a small in-memory, session-scoped static helper (no QSettings, no persistence across restarts -- this is a live "what did I just use" value, not a new app-wide default). Write side hooks capture the value right where the properties editors already apply a change (ShapeGraphicsItemPropertiesWidget::associatedUndo(), both the live-edit dock path and the modal editProperty() dialog path; and IndiTextPropertiesWidget::on_m_font_pb_clicked() right after the font dialog returns). Read side hooks apply the stored value, if any, to a newly created item: DiagramEventAddShape::mousePressEvent for shapes, IndependentTextItem's constructor for free text (falling back to the existing QETApp::indiTextsItemFont() Preferences default otherwise). Doesn't touch the element/symbol editor's own drawing tools (a separate subsystem) or add last-used text color (no color control exists in the text properties UI to originate it from yet).

@brief The LastUsedStyle class
|
|
Session-scoped "last used" style for new shapes and free text created
|
|
on the diagram canvas: whatever pen/brush/font was last applied through
|
|
the properties editors becomes the starting point for the next new
|
|
item of that type, the way most drawing tools behave.
|
|
|
|
Deliberately in-memory only, not QSettings-backed: this is a live
|
|
"what did I just use" value for the current editing session, not an
|
|
app-wide default (that's already covered by the Preferences dialog's
|
|
font setting, read as the fallback when nothing has been set yet).
