You can use Qt Creator to create, build, and run Qt tests, Qt Quick tests (QML-based Qt tests), Google tests, and Boost tests for your projects. 文字列フォーマット C言語では、sprintfを使用してchar配列としての文字列をフォーマット設定することができたが、C++において、std::stringに対する文字列フォーマット機能は、C++14時点で標準ライブラリとしては提供されていない。 Boost Format Libraryは、std::stringの文字列フォーマット、および. The reflecting properties of a parabola make parabolic reflectors useful in many practical applications. For example, flashlights use parabolic reflectors to reflect light from the bulb forward in a concentrated beam, and some solar collectors use a parabolic reflector to concentrate the sun's rays to heat water or generate electricity (see Figure 3, below).

Build a parabolic reflector and measure how it boosts the signal of your wireless router's antenna. This project was originally written by Andrew Olsen, Ph. The antenna in this project is based on the template provided by M. Chances are that you have used a wireless device like a smartphone, tablet, or laptop to access a Wi-Fi network, either at home or in a public place like a library or school.

Have you ever noticed that the signal strength of the Wi-Fi network can vary depending on where you are? The wireless connection is formed between your device and a wireless router. Your device and the router each have an antenna that can broadcast and receive a Wi-Fi signal.

In general, if you get too far away from the router, or if there are certain materials like metal or concrete in between you and the router, the signal will get weaker. How can you improve the strength of a wireless signal, for example, for a computer that has to be much farther away from the router than usual?

One way to do this is by using a parabolic reflector. A parabola , shown in Figure 1, below, is a special mathematical shape — a curve consisting of the points that are equidistant from both a given fixed point called the focal point or focus and a given fixed line called the directrix. Something is truly special about a parabola's shape. Any rays that originate at the focal point will be reflected outward, parallel to the parabola's axis of symmetry.

Хочу, чтобы ты предстал перед ней полостью готовый раскладывать ее по-всякому. Она уехала, а воспоминания о белой и красивой девушке остались навсегда. Потом жадно обхватил ладонями ее красивые титьки и принялся любовно мять их, играя пальцами с твёрдыми сосками. I turned to the door. He was a tall man, balding, but still retained the youthful looks of one twenty years his junior. Смотри на подборке, как жестко он трахает ее в рот и другие дырки.

Signals and slots are used for communication between objects. The signals and slots mechanism is a central feature of Qt and probably the part that differs most from the features provided by other frameworks.

In GUI programming, when we change one widget, we often want another widget to be notified. More generally, we want objects of any kind to be able to communicate with one another.

For example, if a user clicks a Close button, we probably want the window's close function to be called. Older toolkits achieve this kind of communication using callbacks. A callback is a pointer to a function, so if you want a processing function to notify you about some event you pass a pointer to another function the callback to the processing function.

The processing function then calls the callback when appropriate. Callbacks have two fundamental flaws: Firstly, they are not type-safe. We can never be certain that the processing function will call the callback with the correct arguments. Secondly, the callback is strongly coupled to the processing function since the processing function must know which callback to call.

In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal. Qt's widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in.

The Bank or Marcus Bank is a feature added with Mad Moxxi's Underdome Riot , allowing players to store items from their character's inventory. The bank is located in The Underdome.

Access to the bank is achieved by talking to the Claptrap in the tuxedo, who acts as the cashier. The Bank was created as a subsidiary of Marcus Corp.

The Bank is unique to each character on a Borderlands account and will store any of a character's equipment without the worry of clogging up that character's personal inventory. It will carry its own unique orange screen similar to Vending Machines in which items can be deposited or withdrawn from.

Bank storage capacity can be upgraded by buying Bank Upgrades, which can be found in the Red Weapons Vending Machine right outside the bank itself. Bank upgrades can only be purchased from the Red Weapons Vending Machine just outside of the bank. As with any purchasable SDU , they can be purchased at a higher level, without having to buy the intermediate steps.

Higher level bank upgrades become available with playthrough progression. Bank Upgrade Levels 8 and 9 become available in playthrough 2. Bank Upgrade Level 10 becomes available upon unlocking playthrough 2. The bank returns in Borderlands 2 in the form of a large vault door. The maximum space up to 24 slots can be upgraded for higher capacity at the Black Market.
