Not possible right now (unless you package all of PyQt with your plugin).

EDIT: I take that back. If you want to use an externally installed Python interpreter you can use whatever python gui framework you have at your disposal. But if you wanted to share your plugin, you'd have to instruct users how to set up their python environment to match yours.

We supposed that there is already PyQt5 installed on the client computer.
I've these files plugin.py and Formulaire.py.
Can you help me please ? Thanks for answer.

If you already have PyQt5 installed (and you've verified that you can, in fact, do PyQt stuff outside of Sigil), then it should work. You just have to make sure you've unchecked "Use Bundled Python" in Sigil's Plugin Manager dialog, and configured your external Python interpreter.

Yes, PyQt5 run correctly outside of Sigil

There is no checkbox called "Use Bundled Python" on my Sigil (Sigil 0.8.7)

Any idea ?

Have you configured the correct Python interpreter? If PyQt is installed to work with Python3, then you need to make sure you've configured Sigil with the Python3 interpreter (or vice-versa). Also make sure the "engine" tag in the plugin.xml file has the correct PyQt-enabled entry (python34 or python27).

Yes, there is "/usr/local/bin/python3", and other plugins work correctly. Only this test with PyQt5 doesn't work. I'm a beginner too with PyQt5 so I'm trying new stuff.

I'm not near my computer right now, so everything I'm mentioning is off the top of my head. Let me check on this when I get home and make sure I'm not leading you astray on what is possible.

Okay, let me know if you found some solution.
Now, It's work, the widget is working now but it's very slow compared to Tkinter (I don't know why).

PS : Can you help me to delete the post number #184 ?

[DiapDealer]

I'd rather not delete it. It may help someone in the future who's looking to do something similar.

Oh! Duh.

I've found out by chance that it's possible to run JavaScript code in the Preview console window.
Of course, since the read-only Preview window doesn't allow edits, you can only use it for temporary changes. For example, you can highlight certain words.

You can test this with the following simple script, which will highlight all search terms. (BTW, only the first line is by me.)

Spoiler:

// Highlight text example
enteredText = prompt("What do want to search for?");

findAndReplace('(' + enteredText + ')', '<span style="background-color: #FFFF00;">$1</span>')

// code by James Padolsey; http://james.padolsey.com/javascript/find-and-replace-text-with-javascript/
function findAndReplace(searchText, replacement, searchNode) {
    if (!searchText || typeof replacement === 'undefined') {
        // Throw error here if you want...
        return;
    }
    var regex = typeof searchText === 'string' ?
                new RegExp(searchText, 'g') : searchText,
        childNodes = (searchNode || document.body).childNodes,
        cnLength = childNodes.length,
        excludes = 'html';
    while (cnLength--) {
        var currentNode = childNodes[cnLength];
        if (currentNode.nodeType === 1 &&
            (excludes + ',').indexOf(currentNode.nodeName.toLowerCase() + ',') === -1) {
            arguments.callee(searchText, replacement, currentNode);
        }
        if (currentNode.nodeType !== 3 || !regex.test(currentNode.data) ) {
            continue;
        }
        var parent = currentNode.parentNode,
            frag = (function(){
                var html = currentNode.data.replace(regex, replacement),
                    wrap = document.createElement('div'),
                    frag = document.createDocumentFragment();
                wrap.innerHTML = html;
                while (wrap.firstChild) {
                    frag.appendChild(wrap.firstChild);
                }
                return frag;
            })();
        parent.insertBefore(frag, currentNode);
        parent.removeChild(currentNode);
    }
}

(To display the console window, click Console in the grey menu bar below the Preview window; press Enter to run the code.)

EDIT: This script doesn't work with all ePubs. With some ePubs you might get the following error:

Error: SyntaxError: DOM Exception 12

and I haven't got the faintest idea what's causing this.

If it doesn't work with your book, you can test it with Sigil_python_plugins.html from the Plugin Framework guide.

Hi,

as far as i can see there is no method available in the API to just rename a file. I need to delete it and insert it again - but then its position is gone in the spine and i have to add id there again - in the right position.

Did i miss something or is it so complicated?

//rubeus

PS thinking again deleting/adding is not an option (even if i would be able to handle the spine) as it will disrupt any other links pointing to this file.

Renaming means having to do a universal update to find everything that points to it. That code exists in Sigil so renaming is best done inside Sigil itself and not in a plugin to prevent huge duplication of url/href/src and etc link updating code. The purpose of the plugin is to extend Sigil, not duplicate Sigil's functionality.
