Dynamically Update Tooltip Currently Displayed

由 别等时光非礼了梦想. 提交于 2019-12-17 17:11:10
问题 I'm trying to got a tooltip which displays the current progress of a task. So I want that the tooltip text change while the tooltip is displayed. But, when I call setToolTipText() the displayed text remains the same until I exit the mouse from the tooltip component and enter again. And call setToolTipText(null) before doesn't change anything. 回答1: Indeed it does not update itself, even when resetting the tooltip to null between calls. So far, the only trick I found was to simulate a mouse

Loading XAML at runtime using the MVVM pattern in WPF

问题 This is a question that extends from the originally posted here: Link to loading-xaml through runtime I'm working on a WPF MVVM application that loads XAML content dynamically from an external source, very similar as the answer in the post above. Here is what I got so far: My View declares an instance of the ViewModel as a resource and creates an instance of that ViewModel In my ViewModel constructor I'm loading a XamlString property coming from an external source (file or db..)

dynamic JContainer (JSON.NET) & Iterate over properties at runtime

由 大城市里の小女人 提交于 2019-12-17 16:33:50
问题 I'm receiving a JSON string in a MVC4/.NET4 WebApi controller action. The action's parameter is dynamic because I don't know anything on the receiving end about the JSON object I'm receiving. public dynamic Post(dynamic myobject) The JSON is automatically parsed and the resulting dynamic object is a Newtonsoft.Json.Linq.JContainer . I can, as expected, evaluate properties at runtime, so if the JSON contained something like myobject.myproperty then I can now take the dynamic object received

问题 I’ve started with the “Let’s make a bar chart I” example here: http://bost.ocks.org/mike/bar/ And I’m having a hard time figuring out how to make the very simple bar chart made with HTML5 elements update with new data. Here is my code: <!DOCTYPE html> <html> <head> <style> #work_queues_chart div { font-size: 0.5em; font-family: sans-serif; color: white; background-color: steelblue; text-align: right; padding: 0.5em; margin: 0.2em; } </style> <script src="http://d3js.org/d3.v3.min.js" charset=

Difference between &(*similarObject) and similarObject? Are they not same?

由 痞子三分冷 提交于 2019-12-17 16:27:00
问题 Can someone please explain this to me dynamic_cast<SomeObject *>( &(*similarObject) ); What is the point of doing the address of a dereferenced pointer? Wouldn’t the pointer itself just be the address of it? 回答1: It may be that the type of similarObject has overloaded operator* and so it returns something whose address you're passing to dynamic_cast . &(*x) and x may not be always the same thing. For example, think of iterator: std::map<int, int>::iterator it = v.begin(); Then it and &(*it)

jQuery Mobile - Include Footer from External File

由 一曲冷凌霜 提交于 2019-12-17 16:23:39
问题 I would like to create a shared footer (e.g. footer.html) that can be used by all of the pages in my jQuery Mobile application. However, I cannot find a way to get jQuery to refresh the styles in the footer navbar after loading the html from the external file. After thoughts would be greatly appreciated. Footer.html: <div data-role="navbar" class="CSS" data-grid="d" id="footerNav"> <ul > <li ><a href="#" id="a" data-icon="custom"><div>a</div></a></li> <li ><a href="#" id="b" data-icon="custom

How to call DynamicObject.TryGetMember directly?

由 心不动则不痛 提交于 2019-12-17 15:43:23
问题 I'm implementing a general purpose function to extract a value from an arbitrary provided dynamic object, but don't know how to call TryGetMember because it requires a GetMemberBinder which is abstract, hence I cannot create it. Sample... public object GetValue(DynamicObject Source, string FieldName) { object Result = null; GetMemberBinder Binder = x; // What object must be provided? Binder.Name = FieldName; if (Source.TryGetMember(Binder, out Result)) return Result; throw new Exception("The

Dynamic Class Definition WITH a Class Name

由 我是研究僧i 提交于 2019-12-17 15:26:41
问题 How do I dynamically define a class in Ruby WITH a name? I know how to create a class dynamically without a name using something like: dynamic_class = Class.new do def method1 end end But you can't specify a class name. I want to create a class dynamically with a name. Here's an example of what I want to do but of course it doesn't actually work. (Note that I am not creating an instance of a class but a class definition) class TestEval def method1 puts "name: #{self.name}" end end class_name

Can script.readyState be trusted to detect the end of dynamic script loading?

由 走远了吗. 提交于 2019-12-17 15:23:25
问题 I use dynamic script loading to reduce the duration of the initial page load. To ensure that the functions and objects defined by a script are accessible, I need to ensure that the script has been fully loaded. I have developed my own Javascript library to this end, and thus did quite a lot of research on the subject, studying how it's done in different libraries. During a discussion related to this issue, Kyle Simpson, the author of LABjs, stated that: LABjs (and many other loaders) set both
