I'm working on a Qt UI that will run on a touchscreen. At some point it will be useful to select files, in (probably) a QFileDialog.
But little icons on a QFileDialog leads to a terrible touch-user experience, I'd like them to be bigger, so the user doesn't get crazy trying to navigate in the filesystem.
Actually, I'm searching documentation to see if there is a way through css, but haven't seen yet which target/propery to use.
Given the doc of QFileDialog class:
QFileDialog::Detail 0 Displays an icon, a name, and details for each item in the directory.
QFileDialog::List 1 Displays only an icon and a name for each item in the directory.
You can't set icon size this way. I recommend you to set a custom icon provider on the QFileDialog.

I have created my AppleScript, tested it, saved it as an .app and it works.
Now, how do I set a custom icon for it?
I have done a bit of googling and tried a few different things but cannot get it to work. The app is mainly for me and maybe some people I know to make workflows easier so having a nice little icon makes a huge difference.
Can anyone help with this please?
Basically you need an .icns icon file.
Open your application with right-click > Show Package Contents
Navigate to Contents > Resources
Delete applet.icns
Drag the custom icon file into the Resources folder
Rename the icon file in Resources to applet.icns
To update the icon appearance open and re-save the applet in Script Editor.
This is how I do it:
In Finder, select your icon file.
Get Info (CMD-I) on the file.
Click the icon in the top left corner of the Get Info window.
Copy it via CMD-C.
Now Get Info on your AppleScript file.
Click the icon in the top left corner of the Get Info window.
Paste the icon using CMD-V.
The AppleScript icon should be replaced by the icon copied from the icon file.
A screen recording demonstrating this process can be viewed at this answer from AskDifferent.
Just building into #pipwerks answers: You can also use Drag&Drop!
(Optional) Create your icon online from any image on https://iconverticons.com/online/ and download de .icns file for your icon.
Get Info (CMD-I) on you AppleScript file.
Now Drag&Drop your .icns file into the small icon in the top left corner.
It works and now it's ready to add it to the dock or wherever you want.
On newer systems if the above methods do not work there is another solution.
In Script Editor, after opening our script (.app), choose View -> Show Bundle Contents from the menu (or press cmd +0).
In the panel that will expand on the right (Bundle Info) in the Resources section, right-click the applet.icns file and select delete from the drop-down menu.
Our new icon file with the same name applet.icns drag and drop into the window Resources where you just deleted it.
Save application and voila :-D
Here's another way on newer systems, I'm using macOS 12.1.
Open the new icon image file in Preview and choose File > Export...
Hold down the Option key while selecting "Format" and see a whole bunch of new choices including ICNS.
Save it, drop it in your Resources folder, and you're good to go.
icon_expr is gone.
There is an related issue https://github.com/plone/Products.CMFPlone/issues/1236
concerning the problem but only for control-panel icons.
What is the appropriate way to add a icon to a dexterity content type in plone 5?
Any pointer welcome
Volker
Unluckily the Plone 5 way is only through CSS (with a background image for example) and register it in the new resource registry.
One way I tested is to re-use Fontello, like Barceloneta is doing but is not really simple because you must manually modify the generated CSS to prevent you new CSS to destroy other global rules.
An example is here: https://github.com/RedTurtle/TurtledGazette/tree/master/Products/PloneGazette/browser/static (it's not even Dexterity or Archetypes, but this is not important).
Note. I don't really understand this run to CSS and iconfont. It's a kind of over-optimization:
old school images can still be cached
background images are not really accessible as real images provided also an "alt" for blind people, that warn about the content type.
I don't like current situation too much... it's OK while you are developing a theme but is a nightmare for add-ons developers.
Beneath the update of an actual fontello font, you can limit yourself to enhance the icon configuration.
From the Products.CMFPlone package you can get the current icon font config file "config.json"
/Products/CMFPlone/static/fonts/config.json
To review the content of the file visually, go to the fontello.com website and visit the menu under the "wrench" icon.
Reset all icon selections and settings you may have done before.
Unselect glyphs
Reset all changes
Use Import to load the config.json file from CMFPlone.
Review the icons, names, codes and shapes
Look at the source code of config.json and locate icons not referencing a font but containing plain svg path information.
You will figure out that even glyphs can contain multiple path elements and holes as well.
Try to overload just the config.json file in your package by appending your custom icon as plain svg in the json and choose a non conflicting unicode char code. I am still working on documenting this in detail.
Source: I found a hint to this by Victor Fernandez de Alba mentioning this method in his talk [2] (see transscript [1]) during Plone Conf Bucharest:

When I create the "Command link button" (QCommandLinkButton) it has relatively nice green arrow icon.
I would like to see what other nice icons can I choose. When I try to change the icon, [Theme] appears instead of path or some GUI selection dialog:
I also noticed the context menu:
When I click Set icon from theme, again expecting some GUI selection list, I get just a text field:
What I was imagining:
Where's the list of icons from which the green arrow was taken?
QIcon::fromTheme works under specific conditions.
If it can find it in the QIcon::themeSearchPaths() for the QIcon::themeName()
If the desired icon isn't there, Qt Designer won't be able to do any of the from theme, named icons.
But... if you check your target system for the theme search paths and set the theme name, you are more likely to have success.
Example
On linux, I wanted to get a plus and a minus icon.
I found list-add.png and list-remove.png fit the bill.
https://github.com/GNOME/adwaita-icon-theme/tree/master/Adwaita/16x16/actions
http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html
http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
I did a locate on my system and found these:
/usr/share/icons/gnome/16x16/actions/list-add.png
...
/usr/share/icons/gnome/32x32/actions/list-add.png
/usr/share/icons/gnome/scalable/actions/list-add.svg
/usr/share/icons/oxygen/16x16/actions/list-add.png
...
Forcing with fallback icon in QIcon::fromTheme
Find the icon on the filesystem:
ui->toolButton->setIcon(QIcon::fromTheme("list-add",
QIcon("/usr/share/icons/gnome/16x16/actions/list-add.png")));
Find the icon in the qt resource system...
Add the icon in a qrc file in your build, then reference it's path.
ui->toolButton->setIcon(QIcon::fromTheme("list-add",
QIcon(":/list-add.png")));
Overriding the current icon theme
qDebug() << "themeSearchPaths:" << QIcon::themeSearchPaths() << QIcon::themeName();
// themeSearchPaths: ("/usr/local/share/icons", "/usr/share/icons", ":/icons") "hicolor"
The default theme for the system, and for the target deployment machine, likely didn't have the icons in it I wanted... but the gnome or oxygen icon desktop theme installed would almost always have it...
QIcon::setThemeName("oxygen");
Note that you won't see the preview in Qt Designer necessarily because it doesn't set the theme until runtime of your code.
The gnome icon library has 1100+ icons in it. Here is one list:
https://gist.github.com/peteristhegreat/c0ca6e1a57e5d4b9cd0bb1d7b3be1d6a
This works as long as you know what themes are available on the target system.
The list from freedesktop.org has 286 icons listed.
Use icons included in Qt
Just like #peppe pointed out, Qt includes 70 standard icons, too.
widget->setIcon(widget->style()->standardIcon(QStyle::SP_BrowserReload));
http://doc.qt.io/qt-5/qstyle.html#StandardPixmap-enum
Conclusion
Using a stock library on your target system is probably the fastest. Using the Qt built-ins is fast to figure out and use, but is fairly limited. Using a resource file is probably the most robust method, and gives unlimited options on what icon to use.
Be sure to pick a standard icon pack, and think about licensing and attributions, and some other things like that.
And there is no shortage of icons available online:
https://www.quora.com/What-is-the-best-icon-library
https://www.google.com/search?q=open+source+icon+library
Hope that helps.
I don't think that's the function you want to use. The "theme" name there corresponds to the QIcon::fromTheme functionality, which uses icons named according to the FDO specification
http://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html
http://standards.freedesktop.org/icon-naming-spec/icon-naming-spec-latest.html
And they're not really supported on non-FDO platforms (Windows, Mac, ...) unless you deploy your own theme files.
Now some stock icons are shipped with Qt itself; I don't know how to set them from Designer, but from code you can use QStyle::standardIcon:
widget->setIcon(widget->style()->standardIcon(QStyle::SP_BrowserReload));
If the icon you need is not provided by Qt, you'll need to ship it. In that case the Resource System is a convenient way to bundle it alongside your executable.
Last, but not least, from a UX point of view you should consider using QToolButtons unless you're really building a Vista-like wizard.
I'm a GUI developer using Qt targetting cross-platform. Whenever I add a new component of GUI, especially dialogs, buttons, and menus, I suffer for what text I should use.
For instance, when adding a button to select an existing folder, I can think of 3 candidates: "Select", "Open", or "Browse". Also, I'm not sure if I should append ... like Browse... or not.
I have problems to decide the title of dialogs, too. For example, for a dialog to save a file, 'Save', 'Save...', or 'Save a file'...
I do know the specific text may be difference depending on desktop envrironment or OSes, which makes things more complicated.
Is there any reference or guide or library or anything which can help my situation?
There are user interface guidelines on the web:
1) OS X: link
2) Windows: link
3) For KDE i found the following reference: link
4) For GNOME check this out: link
When it comes to "Save" vs "Save ...": I would suggest to use the ellipsis if the user has to activly do something after pressing the button (e.g. choose a file).
I think this should be a relatively easy one to answer, I hope, but is proving to be a bit of a stress!
I have used an Icon on an old application developed some years ago and I would now like to use the icon for a current project.. however..
I added the icon using the upload/import icon-image in the properties window, and did not add it in the project resources file, nor specify its location anywhere in my code, using only the icon tool in the properties window.
Now wanting to find the icon image file to use again, I cannot find it anywhere! I have trawled through all the project files looking for the image file or a ref to its location, but have found nothing; except for:
this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));
When running the application the icon is still clearly visible in the applications taskbar tile.
Does anyone know where the icon file is stored / how I can retrieve it?
Thank you in advance.
It is stored in "{Your_project_name}.{Form_name}.resources" file. Search inside the "obj" folder which is in your project folder.
Now open the command prompt of Visual Studio. We will convert this ".resources" file into a ".resx" file. We use "resgen" command here.
resgen foo.resources bar.resx
The .resx can then be added to a C# project. You can find your icon file there.
