Example 1 with ScreenCoordinates

use of org.rstudio.studio.client.workbench.views.source.editors.text.ace.Renderer.ScreenCoordinates in project rstudio by rstudio.

the class AceEditor method getRangeBounds.

@Override
public Rectangle getRangeBounds(Range range) {
    range = Range.toOrientedRange(range);
    Renderer renderer = widget_.getEditor().getRenderer();
    if (!range.isMultiLine()) {
        ScreenCoordinates start = documentPositionToScreenCoordinates(range.getStart());
        ScreenCoordinates end = documentPositionToScreenCoordinates(range.getEnd());
        int width = (end.getPageX() - start.getPageX()) + (int) renderer.getCharacterWidth();
        int height = (end.getPageY() - start.getPageY()) + (int) renderer.getLineHeight();
        return new Rectangle(start.getPageX(), start.getPageY(), width, height);
    }
    Position startPos = range.getStart();
    Position endPos = range.getEnd();
    int startRow = startPos.getRow();
    int endRow = endPos.getRow();
    // figure out top left coordinates
    ScreenCoordinates topLeft = documentPositionToScreenCoordinates(Position.create(startRow, 0));
    // figure out bottom right coordinates (need to walk rows to figure out longest line)
    ScreenCoordinates bottomRight = documentPositionToScreenCoordinates(Position.create(endPos));
    for (int row = startRow; row <= endRow; row++) {
        Position rowEndPos = Position.create(row, getLength(row));
        ScreenCoordinates coords = documentPositionToScreenCoordinates(rowEndPos);
        if (coords.getPageX() > bottomRight.getPageX())
            bottomRight = ScreenCoordinates.create(coords.getPageX(), bottomRight.getPageY());
    }
    // construct resulting range
    int width = (bottomRight.getPageX() - topLeft.getPageX()) + (int) renderer.getCharacterWidth();
    int height = (bottomRight.getPageY() - topLeft.getPageY()) + (int) renderer.getLineHeight();
    return new Rectangle(topLeft.getPageX(), topLeft.getPageY(), width, height);
}

Example 2 with ScreenCoordinates

use of org.rstudio.studio.client.workbench.views.source.editors.text.ace.Renderer.ScreenCoordinates in project rstudio by rstudio.

the class ImagePreviewer method onPreviewImage.

private static void onPreviewImage(DocDisplay display, DocUpdateSentinel sentinel, UIPrefs prefs, String href, String attributes, Position position, Range tokenRange) {
    // check to see if we already have a popup showing for this image;
    // if we do then bail early
    String encoded = StringUtil.encodeURIComponent(href);
    Element el = Document.get().getElementById(encoded);
    if (el != null)
        return;
    String pref = prefs.showLatexPreviewOnCursorIdle().getValue();
    // skip if disabled entirely
    if (!sentinel.getBoolProperty(TextEditingTargetNotebook.CONTENT_PREVIEW_ENABLED, pref != UIPrefsAccessor.LATEX_PREVIEW_SHOW_NEVER))
        return;
    // display stand-alone links as line widgets (if enabled)
    String line = display.getLine(position.getRow());
    if (isStandaloneMarkdownLink(line) && sentinel.getBoolProperty(TextEditingTargetNotebook.CONTENT_PREVIEW_INLINE, prefs.showLatexPreviewOnCursorIdle().getValue() == UIPrefsAccessor.LATEX_PREVIEW_SHOW_ALWAYS)) {
        onPreviewImageLineWidget(display, sentinel, href, attributes, position, tokenRange);
        return;
    }
    // construct image el, place in popup, and show
    ImagePreviewPopup panel = new ImagePreviewPopup(display, tokenRange, href, imgSrcPathFromHref(sentinel, href));
    panel.getElement().setId(encoded);
    ScreenCoordinates coordinates = display.documentPositionToScreenCoordinates(position);
    panel.setPopupPosition(coordinates.getPageX(), coordinates.getPageY() + 20);
    panel.show();
}
