blend

问题 I searched & read multiple forums about openGL transparency and I found this piece of code gl.glEnable(GL2.GL_BLEND); gl.glBlendFunc(GL2.GL_SRC_ALPHA, GL2.GL_ONE_MINUS_SRC_ALPHA); gl.glEnable(GL2.GL_ALPHA_TEST); gl.glAlphaFunc(GL2.GL_GREATER, 0.1f); gl.glClearColor(0, 0, 0, 0); Some people wrote this code inside the init method and got result.

问题 How can I style thumb using blend. I need to apply a cylinder like style to my thumb. with a gradient color effect. The gradient effect is to be applied vertically with a color combination of gray and white color. I have 0 knowledge in Blend Please help. 回答1: You can do it without using Blend. Simply add a slider in XAML page & open design view. Then right click on slider, open "Edit Template" menu and click on "Edit a Copy". So the default style of slider will be added in page's resource.

问题 i'm trying to make a draggable button in blend. using the dragmovebehaviorelement on a button does nothing, and i think this is because a button already uses the LeftMouseButon_down event. using this behavior on a shape (exp: ellipse) works fine. is there a way to make a draggable button? 回答1: It's not possible to use MouseDragElementBehavior with Button directly because the behavior will never receive the LeftButtonDown event. However, if you are will to change your UI a little, it can be

问题 I've many times done the following: <defs> <filter id="screen"> <feBlend mode="screen" in2="BackgroundImage"/> </filter> </defs> But when I, inside a shape, write "filter="url(#screen)", my shape disappears.

It would help if someone could give me an example that they know works Thanks 回答1: You should try Opera and see the difference. It seems, Opera is the only browser that currently implements this

Result: What I would like to have: Xaml: <Grid> <ItemsControl ItemsSource="{Binding RowSource}" > <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Grid local:GridHelper.RowCount="{Binding RowCount}" /> </ItemsPanelTemplate> <

问题 I have a ListBox which is not virtualizing. I am obviously missing something, but cannot find it. It's actually a ListBox within a ListBox. The outer ListBox has an ItemTemplate which contains an Expander. The Expander is used to display a group of items. The content of the Expander is the second ListBox which displays the items. The ItemTemplate on the second ListBox is bound to the actual Item to display. The ViewModel class for my items has a number of properties which do not initialize
