Apryse SDK allows you to detect and act in response to various events.
Event listeners can be added to a PdfViewCtrlTabHostFragment2 to listen for document viewer events. This can be done by adding a TabHostListener using PdfViewCtrlTabHostFragment2.addHostListener(). Some useful events include:
Event | Description |
|---|---|
| Called when document associated with a tab is loaded. |
| Called when the tab host has been shown. |
| Called when the tab host has been hidden. |
| Called when the last tab in the tab host has been closed, and therefore there are no more tabs. |
| Called when a new tab has been selected excluding the initial tab. |
| Called when navigation button has been pressed. |
Similarly, PdfViewCtrlTabFragment2 has its own events and and you can listen for them by adding a TabListener using PdfViewCtrlTabFragment2.setTabListener(). Some useful events include:
Event | Description |
|---|---|
| Called when the document has been loaded. |
| Called when a new tab has been opened. |
| Called when the tab fragment is paused. |
| Called when download successfully has been finished. |
Touch events, annotation events, quick menu events and tool change events in the document viewer are all managed by the ToolManager. You can learn more about ToolManager events here.
