问题 Can a wx.PyControl contain a wx.Sizer ? Note that what I am ultimately trying to do here (spinner with float values) is already answered in another question. I am particularly interested in layouting widgets within a wx.PyControl , a skill which might prove useful if I come across a need to make my own custom widgets. I already read through CreatingCustomControls, but it didn't use sizers within the wx.PyControl subclass. Using my code below, my CustomWidget just doesn't look right. I'm not

问题 I'm creating a custom control with a property that can take value from a set of strings like "Man, Woman". So in in control designer properties I want to show a combobox with these 2 choices. Is there a standard way to do so ? If not what should I implement ? 回答1: The simple way to do that is to add an enum to your code that defines the possible choices for your property, then configure your custom control's property to accept a value of that type.

问题 I have a user control that contains a textbox and a combobox. I have exposed the combobox's Item property to clients of the user control, thus: public System.Windows.Forms.ComboBox.ObjectCollection Item { get { return baseComboBox.Items; } } I added the user control to a windows form, and set the Items list using the property values editor in the form designer. I then ran the application, and the combobox's drop down list was empty. To confirm that the items added at design time were not in

问题 Short Version I am trying to implement my first ever Component Editor for a custom button I have made. With the help of some online articles I have successfully installed the editor and can see the menu item when I right click on my button in the Form Designer. But this component editor menu is not showing when selecting more than one of my button controls. Do Component Editors only work with single selected controls by default, or can they work with multiple selected controls and if so how?

问题 I'm looking to get a stateless/valueless UIProgressView or other kind of progress bar in iOS: I've tried looking up some documentation but couldn't find anything relevant to my issue. If any of you have any recommendations i'd love to hear those :) Thanks! Shai. 回答1: iOS's UIProgressView is designed specifically for that situation in which you know with certainty the percentage completed of your task. It only provides a 'fill-in' style presentation. You will not be able to use it for merely

问题 I want to create a TextBox where a autocomplete dropdown shows up with some suggestions. Of course, I thought of using AutoCompleteCustomSource on my textbox, but the problem is, that the textbox automatically filters everything that does not contain the entered text. For example, if I type "listen", my algorithm figures "listen (now)", "listen (later)" and "listen to AAA" as suggestions. When I put them in the autocompletecustomsource everything works fine. But as soon as I write "now" so

问题 Is there a way to have a custom control send events that can be used from IB? Something like the events in UIButton's "sent events" (such us touchUpInside) 回答1: Is there a way to have a custom control send events that can be used from IB? No. IB "knows" about the events that UIControl implements, but there's no way to tell it about your own events. 来源： https://stackoverflow.com/questions/9792619/creating-event-for-ib

问题 I'm having a big trouble here. I need to draw a doll in a bed (as in a medical bed), and I can't seem to do it. I tried by creating a custom view, then I started to draw. I used canvas.drawCircle and canvas.drawRect . I managed to draw this doll, but I based it size on the height and width of the custom view, so in the end I couldn't set the angles. Then, I tried to set my custom xml attribute (size), and then wrap its content. But wrap_content didn't work, it was always setting as full
