CSS Grid Layout. Fast start. Basics and support browsers

To open the full GRID potential, you can change the ways to install the size of each row and column. The Grid element supports the following strategies for resizing:

Absolute sizes

The exact size is selected using units independent of the device.

Automatic sizes

Each line and column gets exactly the space that is needed, and no more. This is one of the most convenient dimensions modes.

Proportional dimensions

The space is separated between the string group and columns. This is a standard installation for all lines and columns.

Gridsplitter - separated windows

Each Windows user has met with dividing stripes - moved separators that separate one part of the window from the other. For example, in Windows Explorer, the list is a list of folders, and on the right - the list of files. Dragging the dividing strip, you can set the proportions between these two panels in the window.

In WPF, the dividers band are represented by the GridSplitter class and are GRID tools. By adding GridSplitter to Grid, you provide the user with the ability to change the size of rows and columns.

Most programmers consider GridsPlitter the most intuitive part of WPF. To figure out how to use it to get the desired effect, you only need to experiment a little. Below are some suggestions:

Gridsplitter must be placed in the Grid cell. It can be placed in a cell with existing contents - then you need to configure the installation of fields so that they do not overlap. The best approach is to reserve a special column or string for GridSplitter, with HEIGHT or WIDTH values \u200b\u200bequal to AUTO.

GridSplitter always changes the size of the entire row or column (outside a separate cell). To make the appearance of GridsPlitter with appropriate such behavior, it is necessary to stretch GridsPlitter over the entire row or column, and not limited to the only cell. This uses properties Rowspan.and Columnspan..

Initially, GridsPlitter is so small that it is not visible. To make it convenient, you will need to specify its minimum size. In the case of a vertical separating strip, you need to install VerticalAlignment in Stretch (so that it filled the entire height of the available area), and Width - to a fixed size (for example, 10 independent units). In the case of a horizontal separation band, install Honzontalignment in Stretch, a Height - to a fixed size.

GRIDSPLITTER alignment also defines whether the horizontal type will be (used to change the size of strings) or vertical (to change the size of the columns). In the case of a horizontal separation band, you must install VERTICALALIGNMENT in the center (which is accepted by default), thereby specifying that the separator dragging will change the size of the lines above and below. In the case of the vertical separation band, you will need to install Horizontalignment in the center to change the size of the adjacent columns.

You can change the behavior of the size of the sizes through the properties of the Resisedirection and ResizeBehavior object GridsPlitter. However, it is easier to put this behavior dependent on the alignment settings, which is accepted by default.

Grid is useful, which allows you to conveniently and compactly use to display the frames of the group and raid.

Compactness is that all the players in the group are represented by small squares that can be tuned to their taste. For example, I have a player's health is displayed by the color of its class.

Addon Grid Setup

Addon settings have a very large amount and honestly, most I do not use the majority. The main thing that I was set up is an appearance, as in the screenshot, as well as if health decreases, it decreases from top to bottom.

To open the GRID addon settings, you need to click on the card or in the window if you use this addon.

In the mortgage layout, I set up a display of the number of squares for raid people by 40, because the settings are taken from the currently set raid and if suddenly in the raid there is a dungeon of 10 people, and you are in a raid on Outlo 40-k, then you will have Only 10 people are displayed. Therefore, it is better to set up 40-k and not suffer, it will still be displayed by the number of cells.

The texture that you see on the upper screenshot is called Bentobar and you can change it to your discretion and list of the textures provided. In the same tab, you can specify the size of the boundaries around the player's frame. I personally did them minimal.

Also additional adduction expansion is Addon Grid Mana Bars.That adds strips of manna to Grid, which will be useful to tanks, never paying attention to the number of manna heels. Now they will definitely not be able to not notice this \u003d)

Setting up grid

If Grid was simply a collection of rows and speakers of proportional dimensions, it would be a little sense from it. Fortunately, he is not. To open the full GRID potential, you can change the ways to install the size of each row and column. The Grid element supports the following strategies for resizing:

Absolute sizes

The exact size is selected using units independent of the device. This is the least convenient strategy, since it is not flexible enough to cope with the change in content size, change in the size of the container or localization.

Automatic sizes

Each line and column gets exactly the space that is needed, and no more. This is one of the most convenient dimensions modes.

Proportional dimensions

The space is separated between the string group and columns. This is a standard installation for all lines and columns.

For maximum flexibility, you can mix and combine these different modes of resizing. For example, it is often convenient to create a few automatically changing the size of the strings and then allow one or two other rows to share the remaining space through the proportional setting of the size.

The size change mode is set using the columndefinition width property or the HEIGHT properties of the RowDefinition object, assigning it a number or string. For example:

This syntax came from the world of the Internet, where it is applied on the HTML pages with frames. If you use a mixture of proportional to install sizes with other modes, then a variable string or column will receive all the remaining space.

To split the remaining space by unequal parts, you can assign weight (Weight), which should be specified in front of an asterisk. For example, if there are two rows of proportional size, and it is required that the height of the first was equal to half the height of the second, it is necessary to divide the remaining space as follows:

This will inform Grid that the height of the second line should be twice as much as the height of the first string. To split additional space, you can specify any numbers.

Easily organize software interaction between columndefinition and rowdefinition objects. You just need to know that Width and Height properties are objects such as Gridlength.. To create a gridlength, representing a specific size, simply transmit the corresponding value to the GridlenGth constructor. To create a GridlenGth object representing the proportional size (*), you must transfer the number to the GridlenGTH constructor and the gridunittype.start value as the second argument of the designer. Static property is used to indicate automatic size resizing Gridlength.auto..

Below is an example of the GRID layout with the use of automatic and proportional dimensions:

OK. Cancel.

The record will be useful for newbies, who has never come across the GRID, but wanted to try.
And so what is selenium Grid.. This is a distributed selection of selenium servers for remote browser launch.
And so, first, we need to download the flight version of the SELENIUM-Server-Standalone Jar file from the SELENIUM official site. At the time of writing, this version 3.1.0
After we did, we need to run Hub. (Selenium-Server-Standalone can be run both in Hub mode and in Node mode) HUB is a central dispatcher, which we will register the servers you need and which we will send all requests from tests.

Open the console, go to the directory in which the SELENIUM-SERVER-STANDALONE has downloaded and execute the team:

java -Jar Selenium-Server-Standalone-3.1.0.jar -role Hub

In the console you should have information about the successful start Hub-a.

10: 05: 46.672 Info - Nodes should register to http://192.168.1.121:4444/Grid/register/
10: 05: 46.673 Info - Selenium Grid Hub Is Up and Running

The first line means that we can now register nodes on the URL, where the Hub is running. The second line means
That Hub is successfully launched.

Next, you need to start the so-called nodes (NODE) \u200b\u200bby which the dispatcher (HUB) will distribute the tests running.
Node is essentially an instance of Selenium Server on which the N-O Number of browsers can start.
In this example, I will register and start Selenium Node-s on the same machine on which the Hub is running. Of course you can run the Hub on one remote machine, and node-s on a pile of other remote machines and register on the current hub, actually to this selenium Grid. And need.

Open a new window with a console in which we enter the following command.

java -Jar Selenium-Server-Standalone-3.1.0.jar -ROle Node -Hub http://192.168.1.121:4444/Grid/register/

In this team, we start the node and specify the address of the dispatcher through which all requests will go, the address on which our Hub is running. In my case, it will be http://192.168.1.121:4444/wd/hub, but since in this Hub example, I have been running locally on the same machine on which nodes will be launched, the hub address I could indicate how
http: // Localhost: 4444 / Grid / Register /

In the console we see the information that the node has successfully started

At the same time on the Hub-A console, we see the information that the new node is registered.

10: 54: 27.585 Info - REGISTERED A NODE http://192.168.1.121:5555

Watch the current state of our Selenium Hub, which Node is ready for operation and which browsers are available in them, you can go to the browser bar on the URL, where SELENIUM HUB is running.
In my case, it is http://192.168.1.121:4444/ and from there we go to selenium Grid Hub. console.

In the console, we see that at the moment one Node is connected to the Hub. When Node starts, it cannot determine which browsers are available and therefore the standard configuration consists of 5 chrome browsers, out of 5 FF and 1 IE.

At the same time, on all machines, where you are running Node and where you plan to drive your tests on different browsers, for each browser on the corresponding machine should lie your driver and the PATH variable is configured.
A detailed Node configuration can be viewed by clicking on the Configuration tab of this Node.

When you start the test, you must specify the address of the dispatcher, in my case it http://192.168.1.121:4444/wd/hub
If this test script itself does not know the server address, it knows the address of the dispatcher. All requests go through this dispatcher and are distributed through nodes.

And since the Hub is running on the local computer and one Node is running. And now I will try to start 1 test using the Chrome Browser, specifying the Hub-A address.

In the console, we see that on the node one chrome icon became a buried, it means that the Chrome browser started on the node at the moment and our test goes.

Now let's start 1 more node on our local machine, registering it on all the same our local launched hub.
Open a new console and enter

java -Jar Selenium-Server-Standalone-3.1.0.jar -ROle Node -Hub http://192.168.1.121:4444/Grid/register/ -Port 5556

Since we start the node again locally, on the same machine, then the -Port command is better to specify the port number so that it does not work so that the node will try to start on the port on which another node is running.

We look at the console on the successful startup of the node

In the console with the launched Hub-Ohm we see the information that a new node is registered in the dispatcher

12: 22: 44.566 info - REGISTERED A NODE http://192.168.1.121:5556

At Hub http://192.168.1.121:4444/Grid/console, we now see the information about two nodes.

You can also go to the console of a specific node, in my case it is http://192.168.1.121:555/wd/hub/static/resource/hub.html, where you can stop the session with the browser, create a new, make a screenshot of the screen with the desired browser .

How do we have configured selenium Grid. On one of the projects. We have several powerful machines on which hub and nodes are running. At the same time, on each machine, the triggers that start the batch files in which the starts of hubs and nodes are prescribed with the desired configurations are prescribed. Sample batch file on one of Windows cars

cD C: \\ Users \\ Selenium \\
Java -Jar Selenium-Server-Standalone-3.0.1.jar -role node -hub http://192.168.1.2:4444/Grid/register -Browser browsername \u003d chrome, version \u003d ..., maxinssess \u003d 8 -maxsession 8

The BrowSername parameter means that the Chrome browser must be used on the node.
The -maxInstances parameter sets the maximum number of instances of one supported browser, which can be run on one node.
The -maxSession parameter sets the maximum number of browsers that can be run parallel to one node.

In the next article, I will try to describe my experiments with Selenium Grid Extras.

Grid.- Compact addon for raid or group has the widest settings.
Compactly shows the composition and current status of the raid or party in the form of a mesh for better perception of the raid state when a fluent inspection is very useful for preserving concentration in battle. With it, you can quickly appreciate the situation without losing precious time, do not sharpen attention and not pepper into separate frames of players. It displays really a lot of desired and useful information relating to players. Allows you to configure which information you want to see and how it will be output.
Grid includes modules:

• Health
• Mana / Energy
• Incoming treatment
• Module AGGRO (degree of threat)
• Bafa / Debafa
• Distance
• Pets and vehicles support

Interestingly implemented the submission of information depending on the current state.
To display it can be used:

• Text in the center.
• Icon in the center.
• Frame of the frame of each player.
• Frame transparency.
• Colored squares in four corners.

Since the addon is built on a block basis, for those who understand the adduction, it is not difficult to add new status of modules or displayed indicators. What will give more individuality and will allow even more subtly to adjust the addon to their needs.

The settings menu, though it looks very frightening because of the huge functional, so my advice to you - spend a few minutes to study the opportunity to achieve the greatest informativeness for you.
