- <DxColumn type="buttons">
- <DxButton #default>
- <a href="#" @click="logMyCommandClick">My command</a>
- </DxButton>
- </DxColumn>
- </DxTreeList>
- </template>
- <script>
- import 'devextreme/dist/css/dx.common.css';
- import 'devextreme/dist/css/dx.light.css';
- import DxTreeList, {
- DxColumn,
- DxButton
- } from 'devextreme-vue/tree-list';
- export default {
- components: {
- DxTreeList,
- DxColumn,
- DxButton
- },
- methods: {
- logMyCommandClick() {
- console.log('My command was clicked');
- }
- }
