Hello everyone,
I should note this is my first time posting to a mailing list, so
apologies if I'm messing up something.
We're currently trying to write an editable text editor which has two
modes, edit and view. In edit mode you can make changes using a specific
syntax, and in view mode that is rendered with your usual text-editor
things.
The following features ought to be supported:
* Bold, Italic, Underlined, and strikethrough text
* Different font sizes
* Lists
* Table Of Contents (i.e. hyperlinks that jump to some place in the text)
* Coloured Text
* Aligned Text (horizontal alignment suffices)
* And two special features:
--> Links written in markdown format [display text](link) should be
clickable and emit a signal `linkClicked(QString const& text)` | Note:
They will not be opened in the browser, but rather link to something
else in the application
--> Hovering those links should open a tooltip which is able to render
the HTML4 subset QT provides for all tooltips
I was delighted to see that QTextCharFormat
(https://doc.qt.io/qt-5/qtextcharformat.html) already ships with
`setTooltip` and `setAnchor`/`setAnchorHref`/`setAnchorNames`, however
once I tried to use those, nothing happened.
I scoured around online and found two bug reports, both either
unanswered, or closed. Digging a bit through the source, it seems that
those exact two features are not implemented yet:
https://github.com/qt/qtbase/blob/bef74b6c3a0a9c8649ea8eb333d80015f76863e4/src/gui/text/qtextodfwriter.cpp#L751
The two bugreports:
https://bugreports.qt.io/browse/QTBUG-21553
https://bugreports.qt.io/browse/QTBUG-80524
My questions now are:
1. Is that a really bug, i.e. was it just forgotten? The first bug
report exists since 2011, though I'm unsure of how common it is for
TODOs to exist that long in QTs code base.
2. If not, is there an ETA for those features, or a plan for when
they'll be released?
3. If the answer to 2. is not "very soon", what approach should I take
to implement those features manually. The timeplan for the document
editor was around a month - or at most two, and I'm the sole developer
on it, so I'm looking for something that's doable in that time frame
(I.e. not having to write everything from scratch).
I'm aware of `QTextBrowser`, so combining that with
`QTextDocument::setHtml` would be one option, though I'm unsure if that
would suffice/scale, as we would have to manually reparse user input
into HTML, doable, but certainly not as performant.
Thanks in Advance!
Jonathan Purol
