PUREBASIC OPENWINDOW EXAMPLE INSTALL

Although the example uses a Repeat-Until loop, any type of loop could be used in its place. The second part is known as the event loop, and is the backbone of any window-based PureBasic program. In order to be referenced later, PureBasic also assigns the window an identifier of 0 - the first parameter. The first part builds the interface, and simply instantiates a 300-pixel wide by 200-pixel high window at position 100, 100 on the screen, and gives it a title of My Window. Until event = #PB_Event_CloseWindowThere are two parts to this code.

In the case of a window close event, the loop will be interrupted and the program will end there.Code: Select all OpenWindow(0, 100, 100, 300, 200, 'My Window') If this is a timer event, the temperature is read from the file and displayed in the window. In a loop, the WaitWindowEvent() function waits for the nearest event and returns its code. The AddWindowTimer() function adds a timer to the window with a period of 1000 milliseconds (a second), and an event will be generated regularly at these intervals. Upon successful opening of the file, a window and a text field are created in it by calling the OpenWindow() and TextGadget() functions. If the file is unavailable, a corresponding message appears and the program ends. SetGadgetText(0, StrD(temp, 3)+' ☌') Отображение в температуры в окне.Īt the beginning of the program, the ReadFile() function opens a system file from which the temperature will be read later. SetGadgetFont(0, LoadFont(0, 'FreeSans', 28, #PB_Font_Bold)) OpenWindow(0, 0, 0, 250, 90, 'CPU Temp', #PB_Window_SystemMenu | #PB_Window_ScreenCentered) If ReadFile(0, '/sys/class/thermal/thermal_zone0/temp', #PB_UTF8) = 0 Let’s look at one example that reads the temperature of the “raspberry” processor and displays it in a window. The list can be found in the topic on the official forum To access the raspberry hardware, the community has written a number of libraries or interfaces to existing ones. Small twitching of the picture due to video recording from the screen and its encoding. On the Raspberry Pi 4B, 3D sample applications work fine, even though Raspberry is not designed for 3D graphics. It is enough to specify the subsystem in the compiler settings. This does not require any changes to the code. The Linux version of PureBasic provides a choice of three GUI subsystems – GTK2, GTK3 (default) and Qt. The launch of some of them is shown in the video.

The examples folder contains several dozen different sample programs. The entire process from downloading PureBasic to installing packages and running the test application can be seen in the video.

Their list is given in the INSTALL file and depends on the type of applications being developed. To compile applications, you need to install several developer (dev) packages.
