How to enable this switch?
In the constructor of MaterialApp, there is a bool option called checkerboardOffscreenLayers.

I need to run a function every time the system theme changes from dark to light or vice-versa. Is there a way to fire something off whenever this happens?
You may check this blog , I guess you can put your function in didChangePlatformBrightness() method.

When changing theme to Darkmode with GetX via Get.changeThemeMode(ThemeMode.dark), most widgets change accordingly. But those widgets using some parameter with Get.theme need a hot reload for the effect to take place.
As a comment suggested here, that is because Get.theme is immutable. Using the extension method context.theme does resolve the issue, however, I do not always have access to a context. Get.context.theme does not resolve the issue. What should I do in this case? Since passing the context to wherever needed kinda defeats the purpose of using GetX.
I am not sure what 'some parameters' you are talking about since you didn't include any code, but you can use the Get.changeTheme() method which takes a ThemeData object and changes the theme accordingly without hot restart.
after the tinymce.init() i can toggle the readOnly setting like this:
editor.mode.set("design");
editor.mode.set("readonly");
but how can i toggle the dark theme for the editor and the content?
this will not work:
editor.mode.set.content_css("dark");
editor.mode.set.skin("dark-oxide");
No, it is not possible. All the settings defined in the tinymce.init() function cannot be changed without reinitialization. However, reinitialization can be done very fast. You will need to perform 4 steps:
Save current content somewhere with getContent()
Destroy the TinyMCE instance with destroy()
Reinitialize
Use setContent() to add the content saved on step 1.
As in all languages Debugging is a core concept as we all need to do it:)
I am trying to edit and set a value while running a Flutter App in debug Mode.
However i could not find any place where i can edit the value and set it to test the effect of the change in the flow.
In VS Code i have put breakpoints and run the app in the debug mode.
Set watchpoints etc.. but could not find a way to edit a value?
İs this possible in flutter apps?
I don't think this is possible. In Visual Studio Code there would be a Set Value command on the context menu if you clicked on any variable which you can change, but it is not available when debugging a Flutter application. Even if you go to Debug Console when paused on a breakpoint, and assign a new value to a variable there, it is not reflected when you resume running your code.
I would love this functionality too.
I opened an Feature request on Flutter's github: https://github.com/flutter/flutter/issues/105250
I found a way to be able to change variable values on debug mode in a tricky way.
The idea is to execute a method that changes de value from the debugger.
String variableToChange = 'test';
final changeVariableValue = (String value) => variableToChange = value;
final debbugPointer = null;
In order to make it your you should add the debugger marker in the third line.
Then on the debuuger screen once stoped execute:
changeValue('your new value);
You will see varible has changed on VSCode debuger.
You can use
if (kDebugMode)
doSomething();
I disable org.eclipse.ui.forms.widgets.Hyperlink control just calling hyperLink.setEnabled(false).
However after that the link doesn't looks like disabled control. The link is not grayed out (but I can't click it of course).
The question is: why the link is not grayed out and what should I do to gray out disabled links?
Just extend Hyperlink and set the default colors. Alternatively you could create a composite delegate and forward the interface if it isn't too big - that's probably preferable.
Note that, in addition to Santosh's answer, with Eclipse 4.3 M6, you can restore the default color more easily, since you now have:
A new constant (SWT_COLOR_LINK_FOREGROUND) has been added that will return the native color of hyperlinks on all platforms.
did you try setting gray foreground explicitly ?
you can use following helper method:
public static void setEnabled(Link link, boolean enable){
if(link.isEnabled()!=enable){
if(enable)
link.setForeground(null); // resets to system's default color
else
link.setForeground(link.getDisplay().getSystemColor(SWT.COLOR_GRAY));
link.setEnabled(enable);
}
}
