They are now instance methods on instances of `TextTool`, and won't be static to all tools. ## WebViewer UI ### New #### Customize UI * Simplified Modular UI configs by using the object key as the `dataElement` identifier, removing the need for redundant `dataElement` properties in component definitions. #### General * Custom modal data elements are automatically whitelisted in View Only mode when registered. * Exposed a new `enableMultiSelect()` API for Notes Panel. #### Modular UI * Added new preset buttons: `rotateClockwiseButton`, `rotateCounterClockwiseButton`, `toggleMultiViewerModeButton`, `continuousPageTransitionButton`, `defaultPageTransitionButton`, `readerPageTransitionButton`, `singleLayoutButton`, `doubleLayoutButton`, and `coverLayoutButton`. #### Multi-Tab * Added new API `TabManager.updateTab` to update the `src` or `options` of an existing tab. #### MultiViewer * Added APIs: `getActiveDocumentViewerKey()` and `setActiveDocumentViewerKey(key)` for querying and updating the active document viewer in Multi-Viewer Mode. * Introduced a new event, `instance.UI.Events.ACTIVE_DOCUMENT_VIEWER_CHANGED`, which fires whenever the active document viewer key changes. The event provides both the previous and new keys in its detail payload. * **FilePicker** now loads files in the active `DocumentViewer`. #### Search * Improved search and replace button tooltips to provide clearer, more descriptive labels for better user experience. #### Spreadsheet Editor * Updated the default naming convention for new sheets from "Blank Sheet" to "Sheet" with numeric suffixes for a cleaner, more concise user experience. ### Fixes #### Attachments * Fixed an issue where the UI would lock up attempting to download a large attachment annotation. #### Bookmarks Panel * Fixed an issue where using the Command+B shortcut to add a new bookmark does not open the bookmarks panel. #### ContentEdit * Fixed an issue where transferring focus to different editable text disabled text styling buttons. #### File Picker * Fixed an issue where the file picker would not allow selecting the same file multiple times. #### Focus * Fixed an issue where elements outside of WebViewer were unselectable. #### Fonts * Updated Open Sans and Great Vibes fonts for improved compatibility in Firefox. #### General * Fixed an issue where the Open File Modal did not open encrypted documents. * Fixed an issue where checkboxes continued to appear for notes with multi-select after disabling multi-select. * Fixed an issue where `RibbonItem` tooltips prioritized label property even with defined title property. * Fixed an issue where custom CSS loaded twice when WebViewer initialized with `WebComponent`. * Fixed an issue where the boolean value of the `aria-pressed` property of UI buttons did not update properly when the button was pressed on or off. * Fixed an issue where `setLanguage` threw a warning for custom languages. * Fixed an issue where users were able to specify pages with a period even though it represented an invalid page label. * Fixed an issue in the Notes Panel where the cursor jumped when selecting all text and then typing. * Fixed an issue with Search Panel where the spinner would disappear when closing and reopening the panel. #### Localization * Fixed translations for Hebrew and Arabic. #### Mobile * Fixed an issue where panels were difficult to close or swipe down on mobile devices due to browser pull-to-refresh interfering with swipe gestures. #### Modular UI * Fixed the `ViewControls` component to use the passed `dataElement` prop rather than a fixed `dataElement`. * Fixed `ViewControlsFlyout` to save customizations done via the UI Flyout APIs. #### Multi-Tab * Fixed an issue where closing the password modal and switching tabs would cause the viewer to freeze. * Fixed an issue where save data would leak across different instances of WebViewer if they were both using `MultiTab`. #### Outlines Panel * Fixed issues with the Outlines Panel that were causing errors to be thrown. #### Page Manipulation * Fixed an issue where multiple images could not be inserted using the Insert Page Modal. * Fixed an issue where multiple file uploads were disabled on the page manipulation modals. #### Scale Overlay * Fixed an issue where the scale overlay could not be dragged to the right edge of the viewer when the left panel was open. --- # Agent Instructions This documentation is published with GitBook.
