commit 059ca0f691d567171e7772c1d56a7f96e7867339 Author: Guillaume Munch <g...@lyx.org> Date: Sun Jun 5 21:35:35 2016 +0200Line breaks in tooltips * New function formatToolTip(QString): Format text for display as a ToolTip, breaking at lines of a certain width. Note: this function is expensive. Better call it in a delayed manner, i.e. not to fill in a model (see for instance the function ToolTipFormatter::eventFilter). * Install a global event filter that formats tooltips on-the-fly Inspired from https://github.com/bitcoin/bitcoin/pull/1090/commits/3793fa09ff920fc720dfad3738f105d2c9563662 but much improved. When is formatToolTip called automatically? Whenever the tooltip is not already rich text beginning with <html>, and is defined by the following functions: * QWidget::setToolTip(), * QAbstractItemModel::setData(..., Qt::ToolTipRole), * Inset::toolTip() (added in one of the subsequent patches) In other words, tooltips can use Qt html and the tooltip will still be correctly broken. Moreover, it is possible to specify an entirely custom tooltip (not subject to automatic formatting) by giving it in its entirety, i.e. starting with <html>.
Dear list Tooltips can now be formatted in rich text using qt's html subset (https://doc.qt.io/qt-5/richtext-html-subset.html). Before, this would trigger automatic line breaking with a width which was way too narrow. The patch above gives control over the width. This is used to make the tooltips nicer, especially for bibliographic references in the work area (please try). Tooltips are also automatically formatted now using an event filter that intercepts most tooltips before they are displayed, and also for tooltips in the work area. There is no more need to manually introduce line breaks. If you feel like doing so anyway in some circumstance, please consider whether semantic html tags would be more appropriate. The patch ought to be cross-platform, but if you see anything weird on your platform let me know. Sincerely Guillaume
