Allowing Libraries to add custom Properties to be used in a CustomView in Designer
In the last weeks i have wrapped some libraries. Some of them have their own Properties.
I wish i could write a code in a library which will be called from the designer to get a list of properties.

Possible Types of Properties i saw so far:
- int
- double
- float
- long
- String
- Color
- fontsize
- fontface
- width
- height
- bitmap
- image
- drawable(s)

It would be great if we, the librarydeveloper, could design properties of a new view which then all can be set in the designer

Question: Will existing CustomViews automatically exhibit the custom properties in the designer or will they need to be exposed like the event is?

Good question. I guess @Erel is building something new here. Somewhere in forum he wrote that B4J libraries are not able to use customviewwith designer support at this time and it will be changed in future.

Now, seeing his answer here is guess it is much more than just the possibility to use customviews with designersupport...

It must be more. I like this more; what ever it will be ;-)

Properties will not be added automatically. The view's developer needs to explicitly declare the custom properties.

Another example, this time it is for a B4X class:

SS-2016-01-14_16.16.18.png


SS-2016-01-14_16.13.32.png



The properties are declared like this:
B4X:
#Event: DateChanged (NewDate As Long)
#DesignerProperty: Key: CancelVisible, DisplayName: Cancel Visible, FieldType: Boolean, DefaultValue: True, Description: Whether the cancel button should be displayed.
#DesignerProperty: Key: TodayVisible, DisplayName: Today Visible, FieldType: Boolean, DefaultValue: True
#DesignerProperty: Key: Modal, DisplayName: Modal Window, FieldType: Boolean, DefaultValue: True, Whether the window should be modal.
#DesignerProperty: Key: MinYear, DisplayName: Minimum Year, FieldType: Int, DefaultValue: 1970, MinRange: 0, MaxRange: 3000
#DesignerProperty: Key: MaxYear, DisplayName: Maximum Year, FieldType: Int, DefaultValue: 2030, MinRange: 0, MaxRange: 3000
#DesignerProperty: Key: FirstDay, DisplayName: First Day, FieldType: String, DefaultValue: Sunday, List: Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday, Description: Sets the first day of week.
#DesignerProperty: Key: Title, DisplayName: Title, FieldType: String, DefaultValue: Select Date
#DesignerProperty: Key: BackgroundColor, DisplayName: Background Color, FieldType: Color, DefaultValue: #FFCFDCDC
#DesignerProperty: Key: SelectedColor, DisplayName: Selected Color, FieldType: Color, DefaultValue: 0xFF0BA29B
#DesignerProperty: Key: HighlightedColor, DisplayName: Highlighted Color, FieldType: Color, DefaultValue: 0xFFABFFFB

New class template:

#DesignerProperty: Key: Modal, DisplayName: Modal Window, FieldType: Boolean, DefaultValue: True, Whether the window should be modal.

They can also be added to Java libraries.
How can i use
#DesignerProperty: Key: CancelVisible, DisplayName: Cancel Visible, FieldType: Boolean, DefaultValue: True, Description: Whether the cancel button should be displayed.
in a java-library?

I guess there is now something new like the @commands? Maybe
B4X:
@DesignerProperty(...)
