Tutorials

Each tutorial is a numbered walk-through that ends with a running program. The finished program is a sample project you can download.

Atlas VCL

Atlas VCL: build a window that shows a typed product table in a grid, filters and sorts it, edits it in place, adds validated rows and exports the visible rows as CSV. Project: GridQuickStart.
Atlas VCL interface components: build a themed application shell with a navigation pane, a command bar and a chart page, and keep its layout between runs. Project: ApplicationShell.
Atlas VCL scheduling, printing and PDF: build a window that shows this week's appointments in a TAtlasScheduler week view over a TAtlasSchedule, lets the user move and rename them, and shows an auto-scheduled three-task plan in a TAtlasGantt below it. Project: SchedulerAndGantt.

Atlas Analytics: define a grouped sales report, run it over a table, check the totals and export it to HTML and a print document without opening a window. Project: GroupedReport.

Atlas UI: build a window with a Kanban board whose cards move from code, from buttons, with the mouse and with the keyboard, under a rule that keeps cards from skipping review. Project: KanbanBoard.

Atlas Fin: build a price series in code, lay out a four-pane chart with indicators, check the indicator values and export the chart to PNG and SVG from a console program. Project: CandleChartExport.

Atlas Info: build a customer editor in which every change waits for an explicit Post or Cancel. Project: DataGridEditing.

Atlas Plot Pro: compute quantiles, box statistics, a histogram, a correlation, polynomial fits and a smoothed series on data whose answers you know, check every result, and save a heat map and a box plot to files without opening a window. Project: StatisticsConsole.

Atlas Plot: build a bar and line chart in code, export it as PNG, SVG and CSV without showing a window, and check every file. Project: PlotToPng.

Atlas Virtual Grid: build an in-memory table of orders, show it through a grid with bands and totals, sort, filter and edit it, and export it to CSV, HTML, SVG and PNG without opening a window. Project: MemoryGridExport.

Atlas Crypto: hash text against a published known answer, seal a note with a password and with a key, and see every kind of tampering refused. Project: SealAndOpen.

Atlas Log: set up a logger with a memory sink, a rotating text file and a JSON file, log with templates, a channel, a scope, a failure and a timer, and check the output by reading it back. Project: FirstLogger.

Atlas MQTT: run a broker and a client in one console program, subscribe with a wildcard, publish at every quality of service and prove that each message arrived. Project: LoopbackPublishSubscribe.
