Getting Started - a Qt fast track 3/4 - Widgets and Layouts
summary
Covers building QWidget UIs with Qt Creator and Qt Designer, showing concrete code: use QHBoxLayout/QGridLayout/form layouts, set sizeHint/minimum/maximum, control resizing with stretch factors and spacers, and pick size policies (Minimum, Preferred, Expanding). Demonstrates composing a custom FileChooser (QWidget with QLineEdit and QPushButton, emits filenameChanged) and a working text editor using QPlainTextEdit and QFileDialog — the editor is implemented and running in about three minutes of live coding.
