问题 I have been playing with some sample code which implements a datepicker column for a DataGridView. Where I'm struggling is in how to appropriately access design time parameters (thanks to Bradley Smith for the tip on overriding the Clone method) in the CalendarEditingControl where I want to set the Format to the DateFormat. I've provided the complete sample below and to see where I want to use DateFormat if you just scan for the comment: // * ** * ** * ** * * I'd like to set the Format to the

问题 I'm pretty new to JSF and the many many related technologies out there. I'm trying to make a website that has a header which includes a logo, navigation links, and a login box, such that this header can easily be included in all of the site's pages unless the user logs in, in which case a different header will appear. Something similar to livejournal. I've looked into a few solutions like creating a custom JSF component to handle login and combining that with JSP fragments and/or Facelets.

问题 My Application freezes and LogCat grows heap (frag case) to 14mb if add more then 3 own "components" to current activity/layout. It takes very long until the fourth "component" is added and Android asks to close my application. I've written a Activity which has some components (EditTexts) and a own "component". I want to do something similar to the contacts app (Number adding) but with ingredients. So I've created a class IngredientsLayout which extends LinearLayout and a Layout xml file with

问题 I am trying to use a component which named as A C# IP Address Control but it has a problem I think. because when I increase its value 1, it gives me some wrong result. forexample ipAddressControl3.Text = "192.168.1.25"; IPAddress ipAddress1 = new IPAddress(ipAddressControl3.GetAddressBytes()); ipAddress1.Address++; MessageBox.Show(ipAddress1.ToString()); returns : "193.168.1.25" ! but I expect "192.168.1.26" what is the problem ? here is the components link : A C# IP Address Control edit :

问题 I want to implement something similar to android seek bar.But not in a linear fashion,in an arc shape. is it possible to customize the seek bar in an arc shape? 回答1: You can't make SeekBar to draw its thumb any other way than offset horizontally. The code that actually draws thumb is in AbsSeekBar.onDraw, and there it's seen it's just horizontal offset. You may however make your own widget extending ProgressBar, which would draw thumb whatever way is needed (in arc). But you'll also need to

问题 Im am trying to customize a jScrollPane using the code below. It works, It changes the color the way I want it, but hides the arrowbuttons. What I want is to make them visible again and change them with a custom image. I tried searching on this forum, but I couldnt find any info about it. I hope someone can help me. Thanks in advance! private Image imageThumb, imageTrack; private JButton b = new JButton() { @Override public Dimension getPreferredSize() { return new Dimension(0, 0); } };

问题 The documentation seems to indicate that it is possible to nest custom components within other custom components (http://docs.ractivejs.org/latest/components) : <Foo on-Bar.foo="barfooed" on-Baz.*="baz-event" on-*.bippy="any-bippy"> <Bar /><Baz /><Baz /> </Foo> However, the following code only displays the tooltip. The inner custom components al-tt-translation, and al-tt-input are not initialized. In fact, replacing those two components by a string do not lead to that string being passed in

问题 how do I create a TCustomControl that will behave like Tpanel? eg MyCustomComponent, that I can drop components in like labels, images etc. 回答1: The trick is this piece of code in TCustomPanel: constructor TCustomPanel.Create(AOwner: TComponent); begin inherited Create(AOwner); ControlStyle := [csAcceptsControls {, ... } ]; //... end; There are many more VCL controls you can descend from that have csAcceptsControls in their ControlStyle property. If you want to do this in your own controls,

问题 I have a free hosting service that is stuck in ASP.NET 2.0. Additionally, it constrains users to only inline versions (no codebehind). However, it does allow references to custom components. I have built an inline .asmx and would, ideally, like to 'include'/'use' a component I've built. How do I do this inline? I've tried 'using [Namespace]', but get a compilation error. I've also tried using, in the WebMethod [Namespace of Component].[Method] as well. Again, this produces a compilation error
