OnMouseMove event

Questa voce API conserva identificatori, firme, blocchi di codice e termini PDF nella forma originale.

Fired whenever the mouse moves over the view.

Fired whenever the mouse moves over the view. The Sender parameter references the TPdfView instance that raised the event, so a single handler can serve multiple views by inspecting Sender.

Typical uses include: show a tooltip with the current PDF coordinate, highlight the form field under the cursor, or display "hand" / "ibeam" cursors. Because the handler runs on the VCL main thread, you can update form controls and call other VCL APIs directly.

Handlers must return quickly — PDFium rendering and form filling occur on the same thread, and any delay here postpones the next page repaint.

• Set TabStop to True if you want this control to participate in tab-key focus traversal so that keyboard events are delivered.
• When you assign this event at design-time the IDE generates a stub procedure on the form; you can also assign it at run-time with PdfView1.OnMouseMove := MyHandler.
• Combine with the matching Set Cursor / Set Caret calls on TPdfView to keep visual feedback synchronized.
