Question

我在JInternal框架内加载表时遇到问题，我无法描述它，但我会告诉你一个图像让你理解我的意思。

这是我的代码：

- SparepartController.groovy -

package sparepart

import griffon.transform.Threading

class SparepartController {
    def model
    def view
    def builder

   @Threading(Threading.Policy.INSIDE_UITHREAD_ASYNC)

    def supplier = {
       String id = 'supplier'
       def (m, v, c) = createMVCGroup('supplier', id, title: "Supplier")
       builder.desktopPane(view.desktop) {
           widget(v.window)
       }
    }

    def logout = {

    }

    def quit = {
        app.shutdown()
    }
}

- SparepartView.groovy -

package sparepart

actions {
    action(id: 'loginAction',
            name: 'Login')
    action(id: 'logoutAction',
            enabled: bind {model.auth},
            name: 'Logout',
            closure: controller.logout)

            name: 'Jenis Barang',
    )
    action(id: 'barangAction',
            name: 'Barang',
    )

Answer 1

使用JTable / JTree / JList的简单方法是使用GlazedLists（http://www.glazedlists.com/），幸运的是有一个glazedlists插件http://artifacts.griffon-framework.org/plugin/glazedlists

Answer 2

在您的SupplierController.groovy中，有以下内容：

sql.eachRow("SELECT * FROM tblsupplier") {
   // Look here!
   Map baris = [kodeSupplier: model.kodeSupplier, namaSupplier: model.namaSupplier, 
      alamat: model.alamat, telp: model.telp, email: model.email]
   ...
}

您永远不会使用从SQL查询返回的值。根据您的代码，model.kodeSupplier可能为null。你的意思是it.kodeSupplier？

顺便说一下，对于这种应用程序，我使用这个plugin来生成基于域类（from here）的MVCGroups。使用域类比使用地图更容易。
