问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . Please list GUI programming libraries, toolkits, frameworks which allow to write GUI apps quickly . I mean in such a way, that GUI is described entirely in a human-readable (and human-writable) plain text file (code) code is terse (1 or 2 lines of code per widget/event pair), suitable for scripting structure and

Prolog List Plateau

由 喜你入骨 提交于 2019-11-28 08:40:58
问题 Just got introduced to prolog, trying to get through some simple exercises, but I've been getting kind of stuck on this one. I'm trying to write a program that outputs all the sublists of the input list, where each sublist has length > 1 and it cannot be extended to a larger sublist. It will also output the starting position in the list of the sublist. So a sample output would be | ?- plateau([a,a,b,2,2,2,a+1,a+1,s(1,2)], I, Len). I = 1, Len = 2 ? ; I = 4, Len = 3 ? ; I = 7, Len = 2 ? ; no I

ASP.NET masterpages: how to insert markup in the head section inside the aspx?

由 孤者浪人 提交于 2019-11-28 03:36:32
问题 I know I can access the head section of a page which uses a masterpage programmatically this way (in code behind): This is only an example (I'd like to insert scripts and styles etc.): this.Header.Title = "I just set the page's title"; Is there a simple way to do this in a declarative way on in the aspx file itself ? Sometimes it would be handy to insert a client script or a style declaration or a link to an external resource. 回答1: You can do this by using content regions in the head , in

suggestions for declarative GUI programming in Java

I wonder if there are any suggestions for declarative GUI programming in Java. (I abhor visual-based GUI creator/editor software, but am getting a little tired of manually instantiating JPanels and Boxes and JLabels and JLists etc.) That's my overall question, but I have two specific questions for approaches I'm thinking of taking: JavaFX: is there an example somewhere of a realistic GUI display (e.g. not circles and rectangles, but listboxes and buttons and labels and the like) in JavaFX, which can interface with a Java sourcefile that accesses and updates various elements?

SQLAlchemy declarative syntax with autoload (reflection) in Pylons

由 ＊爱你＆永不变心＊ 提交于 2019-11-27 18:19:48
问题 I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_ init _.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ =

What is declarative programming? [closed]

由 若如初见. 提交于 2019-11-27 09:59:42
I keep hearing this term tossed around in several different contexts. What is it? 1800 INFORMATION Declarative programming is when you write your code in such a way that it describes what you want to do, and not how you want to do it. It is left up to the compiler to figure out the how. Examples of declarative programming languages are SQL and Prolog. The other answers already do a fantastic job explaining what declarative programming is, so I'm just going to provide some examples of why that might be useful. Context Independence Declarative Programs are context-independent . Because they only

Dynamic Class Creation in SQLAlchemy

由 本秂侑毒 提交于 2019-11-26 09:23:57
问题 We have a need to create SQLAlchemy classes to access multiple external data sources that will increase in number over time. We use the declarative base for our core ORM models and I know we can manually specify new ORM classes using the autoload=True to auto generate the mapping. The problem is that we need to be able generate them dynamically taking something like this: from sqlalchemy.ext.declarative import declarative_base Base = declarative_base() stored={} stored[\'tablename\']=\'my
