gwt - Create custom widget and allow nested sub-elements in UiBinder -

-

I want to create a custom widget that allows the UIB to specify its nested sub-element in inder like Dockpanel may be south , answer , etc. I looked at the source code of DockPanel but found a solution. 

  & lt; My: LeftRightToolbar & gt; & Lt; Left & gt; & Lt; Six buttons / & gt; & Lt; / Left & gt; & Lt; True & gt; & Lt; Six buttons / & gt; & Lt; / True & gt; & Lt; / Mary: LeftRightToolbar & gt; My custom  & lt; Left & gt;  and  & lt; Right>  can have multiple sub-nodes

update: code>? Code if I add more than one widget does not compile.

First of all - and lieutenant; Left & gt; and & lt; True & gt; should be in the same namespace as the LeftRightToolbar , so it and & lt; My: right> .

Secondly, you need to annotate two methods in LeftRightToolbar with comment: 

  @iChild (tagname = "left") Add Zero (widget widget) {left.add (widget); } @IiChild (tagname = "right") Zero addToRight (widget widget) {right.add (widget); }

Method addToLeft to & lt; My: left & gt; The tag will be asked to add the specified widget & lt; My: right> The tag is controlled by the addToRight .

If you want to add multiple widgets to your custom tags, then in the container, like FlopNell .

python - mayavi mapping a discrete colorbar on a surface -

I want to change the color of the surface on the basis of another value (an ID) that is considered discrete (hence I In the simplified example given below, I have prepared a field with 3 different IDs: 0 / red on left 2 / blue 1 / green left But with the code below, I have some strange behavior on the border between red and blue (green Point) I think this is probably due to an interpolation! Code: import from import mlab np # np # my dataset -simplified-x, y, z = np.mgrid [-3: 3: 100] H, -3: 3: 100h, -3: 3: 100 h] value = NP. SQLT (x ** 2 + y ** 2 + z ** 2) # My color value: Volume is divided into 3 sub-versions taking colorvalues ​​with X = np.empty (values.shape) colorvalues [0:33,:,:] = 0 colorvalues ​​[33:66,:,:] = 2. Look [66:,:,:] = 1 src = mlab.pipeline.scalar_field (value) src.image_data.point_data.add_array (colorvalues.T.ravel ()) (1) .name = 'MyID' src.image_data. point_data.update src.image_data.point_data.get_array () # surface, contour = mlab.pipe...
