I need to make a field with 2 columns in it. Instead of overriding the layout() and draw() methods, I'm looking for something easier, something like using HorizontalFieldManager. Is that possible?
You can use Blackberry Advanced UI Toolkit containers
com.blackberry.toolkit.ui.container.TwoColumnField
com.blackberry.toolkit.ui.container.TwoColumnFieldManager
Use GridFieldManager for that. See the Java Development Guide "Create a grid layout"

Is it possible to add a package in the reflection-config.json?
Something like:
[
{
"name" : "org.apache.tinkerpop.shaded.kryo.serializers.*",
"allDeclaredConstructors" : true
}
}
Instead of doing it one by one.
Thanks :)
As far as I know, that isn't possible yet. There is an open feature request for this: https://github.com/oracle/graal/issues/1236
Probably the best would be to create a Feature class which would register classes for reflection programmatically. Here's a short example: https://www.graalvm.org/reference-manual/native-image/Reflection/#configuration-with-features
The feature class needs to be on classpath then referenced using the --features= command line option.
I am using tracing agent features to auto generate a list for reflection/jni/resources, this should be quite convenient until one day the wildcard features is implemented. (I bet it will not be implemented due to performance concern.)
I am working with angular_dart and angular_components (material).
I am trying to use a material-dropdown-select with long strings. However, the max width of the popup is limited to 448px, hard-coded. (see source)
What would be the best way to edit / inherit / override that component, so that I can specify the width I want?
Thanks!
Found a solution:
1) Add PopupSizeProviderDirective in the directives of the parent component
2) Use something like ....
I'm trying to write a custom field editor that will translate between Long and String. IE: String representation on screen but field type is a Long.
I've implemented the PropertyEditor (HrMinPropertyEditor) but don't know how to wire it in. My HrMinField is quite clunky as I needed to use a TriggerFieldCell because the generic types inside TextInputCell etc. prevented me from using them.
Do I need to do a subclass of ValueBaseInputCell? That seems strange since my PropertyEditor has all the Long / String conversions. It also looks difficult.
If so, is there a simple example or some documentation I can read?
BTW, my learning project is Maven based and should be easy to fire up if necessary:
svn checkout http://subversion.assembla.com/svn/freshcode_public/learn/gwt/ learn-gwt
cd learn-gwt
mvn gwt:run
Navigate to GXT | Forms | Time Edit
Thanks in advance,
Pete
PS: I've asked this on the Sencha forum too.
You should use method setPropertyEditor from Field class to specify your custom property editor:
HrMinField f = new HrMinField();
f.setPropertyEditor( new HrMinPropertyEditor() );
I managed to come up with a solution using a Converter and a Validator.
The more complete answer is on the Sencha thread.
I use TEasyListView from mustangpeak.net. I'd like to create a combobox in a column. I can't find any sample to do this from the component demo. If I use TListView, I could follow a trick from http://www.swissdelphicenter.ch/en/showcode.php?id=801 but I need to use TEasyListView. Please, give me some guides.
I am not sure but I would guess TEasyListView is a descendant of TListView since pretty much everyone creates new components based on lower level components. Try checking back into the components and you will more then likely find a way to use the "trick" you named above.
Exist any similar component to theme a stringrid like the ThemedDBGrid component compatible with delphi 5.
Surely you could take the source from ThemedDBGrid and re-work it for a stringgrid? Or you could use a DBGrid and wrap your strings up so that they can be accessed through a dataset.
TMSSoftware's Advanced String Grid is pretty popular:

You could also look at skinning components that skin the built in grid, such as:
