When I went back last night, I thought the component object was too simple. I thought it was too much content. It was necessary to add two additional articles to explain other component concepts. Today, we will introduce the processing process of the swing component painting method. This process can help us understand many swing mechanisms.
The painting method of the swing component is an internal interface method. Generally, you do not d
Source: instructor Cheng of China author: the effect of this tutorial has been described in many tutorials. General Idea: first draw a curve with steel strokes, then draw a line and then define it as a brush. Lines must be used in this step. Other effects are not obvious. Then you can use a paint brush or a path stroke to create the desired effect. The author of this tutorial draws silk with a paint brush.

Set the paint effect when creating the image, use a pen to draw the desired path, and then draw the stroke. It is best to adjust the color. Final effect 1: Create a quot; Layer 1 quot; and fill it with black. 2. quot; to do a good job, you must first sharpen the Tool amp; q Source: author of
Description
In a country there is n cities connected by M one to roads. You can paint any of these roads. To paint a road it costs D unit of money where d are the length of that road. Your task is to paint some of the roads so, the painted roads can be partitioned into some disjoint cycles such that E Very vertex appears in exactly k of these disjoint cycles. B
Topic:There is a row of n houses, each house can is painted with one of the three colors:red, blue or green. The cost of painting a certain color is different. You had to paint all the houses such, that no, and adjacent houses have the same color.The cost of painting a certain color was represented by a cost nx3 matrix.
