Recently turned up the Raspberry Pi I bought before, and decided to pick up the Raspberry Pi combined with the go language that I was learning to engage in things. Here first build the environment to run the GO program.
First, the Raspberry Pi installation
Environment: Raspberry PI 3 B, WIN10, 16G CLASS10 TF card, card reader, Advanced IP Scanner, Mobaxterm, go1.8.3.linux-armv6l.tar.gz

Android introduced this kind of PNG extension format to solve the problem that the same picture is deformed after being stretched, which provides an elegant solution for resource reuse.Tools:To preview or edit a 9patch image, use the Draw9patch tool that

For example, if you need a 3x screen, you can do the highest image directly.5, and when using the vector tools such as flash to do the material, you should do a bit of that size directly. For example, a button with a 66-point x. Create a scene with a x 66. Then it is exported to twice times the graph, 3 times times the graph, because the vecto

I don't use much, I still need to learn the basic usage. Maybe one day can be used!
If you say yes, you have nothing to learn! Let's get started with this section. We will learn this section.
The third layout in Android: TableLayout (table layout )!
1) This section describes the road map:
Roadmap analysis:
From the above roadmap, we can see that TableLayout is easy to use. It is nothing more than determining the number of rows in the table and using
The three attributes are used to hide,

Therefore, the interval between items is one times larger than the interval between items and borders.

Once upon a time, the project has met the demand for video proportional stretching, but found this seemingly ordinary but a demand, search all over the net has not found a solution. Because the force to set the width and height of the video label will only stretch the display area, but the videos inside the original ratio, how to tune is useless:
Because when I stretch horizontally:
When I

If __name__ = "__ main__ ":
app = Qapplication (SYS.ARGV)
ex = Example ()
sys.exit (App.exec_ ())
We use the move () method to place the control. In the example we place the label by setting the x, y coordinates. The origin of the coordinate system is in the upper-left corner of the form. The x axis grows from left to right, and the y-axis grows from top to bottom.

In the Android design process, in order to adapt to different mobile phone resolution, most of the pictures need to stretch or compress, so that there can be arbitrarily resized a picture format ". 9.png".
The picture is a special image format for Android development, and the advantage of this is that you can use a simple way to stretch which areas in a picture, which areas cannot be stretched, and to mark
above image, after using sliced mode, Depending on the frame of the picture, the four corners of the picture remain intact, while the 1 and 4 sections stretch as the picture stretches horizontally, and the 2 and 3 chapters stretch as the picture stretches vertically, and the middle part of the picture stretches 5 to fill.
Fill Center: When checked, 5 is displayed, whereas 5 is not visible.

5.3 Image Objects Overview
5.3.1 Tgraphic Object
The Tgraphic object is the base class of the Tbitmap, Ticon,tmetafile object. If you know the exact type of the image (such as a bitmap, icon metafile), you should store the image in the appropriate type of object (such as Tbitmap,ticon,tmetafile), or you should use a Tpicture object that stores any image type.
5.3.2 Tpicture Object
Tpicture objects can save bitmaps, icons, or meta files. The graphic property includes the type of the image, th
GridBagLayout is one of the most important layout managers in Java, can make a very complex layout, can say that gridbaglayout is necessary to learn,GridBagLayoutClass is a flexible layout manager that does not require components to be of the same size to align components vertically, horizontally, or along their baselines.Each GridBagLayout object maintains a dynamic rectangular cell grid, each of which occupies one or more of these units, which is called the display area .Here is a Notepad case
