Nesta aula, vamos aprender os controles de seleção e alternância do WinUI 3 C++.
| Nome original do controle | Nome em português |
|---|---|
| CheckBox | Caixa de seleção múltipla |
| RadioButton | Botão de rádio de seleção única (mutuamente exclusivos no mesmo GroupName) |
| ToggleSwitch | Interruptor deslizante |
| ComboBox | Caixa de seleção suspensa |
| ComboBoxItem | Item da lista suspensa |
| ListBox | Caixa de lista de altura fixa (sem virtualização) |
| ListBoxItem | Item da ListBox |
| SelectorBar | Seletor segmentado horizontal |
| SelectorBarItem | Item da aba segmentada |
| TreeView | Visualização em árvore hierárquica |
| TreeViewItem | Nó da árvore |
| RatingControl | Controle de avaliação por estrelas |
Abaixo temos um exemplo demonstrativo desses controles comuns.
Pode haver pequenas diferenças entre versões do SDK; o vídeo usa o Visual Studio 2022.
