Eclipse WikiText: How to set css for preview? - css

Using Eclipse 2020-09 (i.e. v. 4.17) IDE for Java (on Linux, openSUSE Tumbleweed), with version 3.0.38 of Mylyn WikiText plugin installed, I had the following difficulty: Although pretty much all editor/ui fonts were fine, the HTML preview of WikiText files (in particular README.md!) displayed in unreadably small fonts (my display has a very small pixel pitch). So I wanted to find a way to set the CSS of such preview pages. The Mylyn WikiText docs (at https://help.eclipse.org/2020-09/index.jsp?topic=%2Forg.eclipse.mylyn.wikitext.help.ui%2Fhelp%2FMylyn+WikiText+User+Guide.html, under the heading "Rendering Appearance") says that there should be a Preferences screen General > Editors > Text Editor > WikiText > Appearance that allows one to set this CSS. However, no such screen shows up in my installation.
The only method I was able to find for fixing this was to use an application (such as Engrampa) which is able to edit the contents of .jar files, and in my eclipse installation directory, use it on plugins/org.eclipse.mylyn.wikitext.ui_3.0.[SPECIFIC_VERSION_HERE].jar to edit the internal component org/eclipse/mylyn/internal/wikitext/ui/viewer/default.css -- I could change any css there, and upon restarting Eclipse, the changes would take effect.
However, clearly any changes I make this way will be blown away upon the next update of Eclipse or of Mylyn Wikitext. Does anyone know of a better way to set the size of the preview text? Was that Appearance pane mentioned in the docs removed? If so, what replaced it? If not, any ideas why I might not be seeing it?

Visual Studio 2022 ASP.NET Core 6 Default application and Add folder to workspace in Chrome DevTools is not working anymore

After some update to either Visual Studio (I have the same issue in both VS2019 and VS2022) or Chrome I can no longer update the CSS in DevTools and have it reflect and persist the changes to site.css file in my project. Instead when I try to change a CSS property I get the following in the DevTools console:
Unable to find a stylesheet to update. Updating all local css files.
15:54:01.800 aspnetcore-browser-refresh.js:82
And the green dot disappears from my CSS pane immediately after I hit the up or down arrow on my keyboard to try and change the CSS value.
Why is that? It used to work not too long ago. I think it's been broken for me for half a year or so now.
I've been googling but haven't find any good resources. Or maybe I'm the only one coding directly in Chrome? :) Surely this can't be the case?
If anyone knows a workaround please share because I'm really frustrated atm :)
Disabling "Enable CSS Auto-Sync" seems to do the trick.
Update 1: The above no longer works for me for some reason. I managed to find another fix on SO: https://stackoverflow.com/a/70096917/687549
And here are some screenshots:
Update 2: Update 1 works when you only need to update the CSS directly in Chrome. It's better to have Hot Reload enabled and the set the following setting to None - then you'll get the best of both worlds (Hot Reload + Edit CSS directly in Chrome using workspaces): https://stackoverflow.com/a/68954979/687549
Update 3: I'm now using VSCode. If none of the above works try the following (block .js file in Network tab in Chrome DevTools): https://stackoverflow.com/a/68966524/687549

How do "theme" icons work in Qt Creator Designer?

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.

How to change JavaFx native Bundle exe icon

I am trying to chance the icon of the exe file created native bundling of javafx packaging but it still contains the default icon. Please suggest
primaryStage.getIcons().add(FileUtility.loadImage("icon.png"));
did not help, it only changes the title bar and task bar icon.
The ico file still gets generated and icon of the exe files remains the default one
I also tried to assign an icon in the project properties-> Deployment-> icon but did not help
I believe I have encountered the same issue and the solution is described in the following thread.
As a side note - neither specifying your icon in the build.xml file or via the project's options in the deployment section is going to work thus far, but it seems to be fixed in the upcoming release of 7u10.
I added response here How to set custom icon for javafx native package icon on Windows and thinks it is the same issue you started out with. However you seem to have moved on, but others might find it interesting...
I added src/main/deploy/package/windows/myapp.ico there and it finally worked :)
For you:
Create src/main/deploy/package/windows/ folder
Add icon with name ${project.build.finalName}.ico
Run mvn jfx:build-native
I haven't played with it extensively - just got it to work and wanted to share. So if you want to use icon with different name, I don't know how. Not yet at least. The ... section in the config section seems to be for webstart, so I haven't been using it. Hope you get it to work!

Adobe AIR: Controls flipped (mirrored) in certain build environments

I'm having an issue where certain controls are flipped, depending on the machine that I'm building my project on. On my development machine, when I build it, everything is okay. However, when I build it on our build server, some things are flipped. It seems to be things that are on a higher layer - for instance, options in the select control (see first image below), alerts/overlays (see second image below), etc. It's not just the text, either - the entire content is flipped, images and all.
I have verified that the code is exactly the same in both instances, so it must have something to do with settings or the flex SDK version. On my development machine, the Flex SDK version is 4.0.0.14159, and on the build server, the Flex SDK version is 4.1.0.16076. I can downgrade the SDK on the build server if needed - but could it really be an issue with the SDK? Any ideas?
Thanks!
It looks like this will be fixed in the 4.5 SDK--see SDK-26473 for workarounds.
I was able to fix the mirroring by turning off Flex 3 Compatibility Mode in the Flex compiler settings (if using mxmlc, -compatibility-version=4.0).
Your build machine must be set to a locale which uses right-to-left text, such as Hebrew or Arabic keyboard setting.
Oops - hadn't read all of dpstone's answer before I posted my comment to the question.
The answer to this problem is in the bug he linked to. You need to explicitly set the layout direction. You can do this in one of two ways.
1) in a .css file that you import into your main application file:
global
{
layoutDirection: "ltr";
}
OR
2) you can set it in a <style> tag in your main application file.
<mx:Style>
global
{
layoutDirection: "ltr";
}
</mx:Style>

Export CSS changes from inspector (webkit, firebug, etc)

When I'm working with CSS, I'll often test in a browser - say, Chrome - right click an element, click Inspect Element, and edit the CSS right there. The use of arrow keys to change things like margin and padding makes lining things up super easy.
It's not too hard to then take those changes and apply them to the CSS file, but it would be cool if I could just right click the selector in the inspector and select "export" or "copy", and have the contents available in my clipboard.
Does something like this exist?
I have found the answer to this, at least as of Chrome v14.
While in the Elements section, just click on the "filename:linenumber" link next to the CSS rules. The CSS file that shows up will contain all of the modifications.
This place exactly:
In Chrome, you can right-click a CSS file in the Sources tab and click "Local Modifications"
This shows you all of your local changes. Each revision is timestamped and you can rollback to any previous revision.
See the Live Editing and Revision History section of this tutorial.
Firediff is a Firebug add-on that tracks changes done in Firebug. It logs everything you'll do in the HTML pane (great) but also your brief use of the Web Developer Toolbar extension (not so great), say Shift-Ctrl-F to obtain a font-size information in px.
I have seen a Firebug extension in Chrome but didn't test it, I use Firediff with Firefox.
In Chrome there is also the Changes tab in the console drawer that displays all the modifications of CSS. It's not an export, but at least it is very convenient to quickly grasp what has changed.
I built a Chrome extension that does exactly this.
It's called StyleURL - it takes whatever CSS changes you made in Chrome Inspector and outputs valid CSS as the diff: https://chrome.google.com/webstore/detail/styleurl/emplcligcppnlalfjknjbanolhlnkmgp
Here's an example where I added "padding-bottom: 50px" to this page:
It's open-source and on GitHub too: https://github.com/Jarred-Sumner/styleurl-extension
Both Firefox and Chrome support this feature now, but worth to note that in some platforms if not all Chrome does not show it by default, you need to enable the "Changes" view to see it (in my Kubuntu Linux 20.04 it wasn't by default), here is how you can enable it: go to the "Customize and Control DevTools" button in the Developer Tools bar > "More tools" > "Changes", then the tab will appear at the button:
In Firefox there is no need to enable it, but if you come from the Chrom* world may be hard to find it. Just check the last section in the right at the "Inspector" tab:
I've suggested this product on SO before (I'm not affiliated with them in any way).
http://www.skybound.ca/
Excellent product. Sounds like exactly what you're looking for and much more.
EDIT: Several other answers here have mentioned Google Chrome's ability to link to your local files (which is very very cool). Check out the other answers!
If you edit external CSS, then you can drag its latest revision out of the Resources panel into any text editor that supports DnD (see http://www.webkit.org/blog/1463/web-inspector-styles-enhanced/, the "Persisting Changes" section for more detail.) You can also revert your CSS changes to any earlier version of the stylesheet resource (in the right-click popup menu of any stylesheet revision.)
As mentioned by cloudworks, the answer to this has changed. This can now be accomplished rather well by the Chrome DevTools Autosave extension. This tool tracks CSS and JavaScript changes made within the Chrome Developer Tools console, and saves them back to local files. For instructions to install and setup the extension, please refer to the guide written by #addyosmani on his blog, here.
There is also a handy screencast which details the extension rather well.
With Workspaces you can have your CSS saved as you type them in your inspector (in Chrome). The problem is that every change is automatically saved and there's no way to disable this feature, as pointed in http://www.html5rocks.com/en/tutorials/developertools/revolutions2013/ and Disable automatic saving of CSS changes in Chrome Developer Tools.
My in-beta-soon product LIVEditor does this exactly.
To let you understand it easily, you can think of Firebug's inspector is embedded into your text editor.
That way you don't have to make the changes manually again in your code editor after you tweaking it using Firebug or Webkit's developer tools.
If you're using the Firefox stock dev tools you can edit the css directly in the tools dialog - click the CSS viewport button (that's the button at the top with the {} symbol) and edit your css directly. It will update in realtime in the browser and when you're done just copy-paste it directly into your css file. Nice!
To add an answer for Safari specifically — it's kind of possible.
When you edit CSS in the Styles section in the Inspector for an existing CSS file, you can hit Cmd-S to re-save the entire file with the changes. However, if you're using a meta language like Sass / preprocessor / generating your CSS with bundling etc, I don't think this really solves that problem, though it may be possible with CSS source maps.
When you edit CSS at the top of the Styles section, under Style Attribute to add inline styles (not tied to an existing CSS file), it doesn't seem possible to easily export all of those changes. For now, I'm just copying and pasting the overrides manually for each element.
The official Apple docs are a little dated but found here: Web Inspector Tutorial - Editing Code to Change Your Webpage.
In Chrome, in the css inspector you can click and hold the + button, then choose to add your changes to the inspector-stylesheet. It's not as convenient as directly editing in your css-selectors, but what you write will all be in inspector-stylesheet.css
