RfDzDeveloper's questions

Tentei muitas maneiras diferentes de estender minha mesa para o restante do espaço livre do aplicativo.

A maneira mais simples de reproduzir meu problema é:

package main

import (
    "fmt"
    "strconv"
    "time"

    "fyne.io/fyne/v2"
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/container"
    "fyne.io/fyne/v2/dialog"
    "fyne.io/fyne/v2/theme"
    "fyne.io/fyne/v2/widget"
)

type Reminders struct {
    ID        int64
    EventName string
    EventDay  time.Time
}

func getReminderSlice() [][]any {
    var slice [][]any

    reminders := []Reminders{{ID: 0, EventName: "First Event Name", EventDay: time.Now()},
        {ID: 1, EventName: "Second Name", EventDay: time.Now()}}

    slice = append(slice, []any{
        "ID",
        "Event Name",
        "Event Day",
        // "Start At",
        // "End At",
        // "Event Duration",
        // "Event Place",
        // "Priority",
        // "Description",
        "Delete?",
    })

    for _, r := range reminders {
        var currentRow []any

        currentRow = append(currentRow, strconv.FormatInt(r.ID, 10))
        currentRow = append(currentRow, r.EventName)
        currentRow = append(currentRow, r.EventDay.Format("2006-01-02"))
        // currentRow = append(currentRow, r.EventStartHour.Format("15:04"))
        // currentRow = append(currentRow, r.EventEndHour.Format("15:04"))
        // currentRow = append(currentRow, strconv.FormatFloat(r.EventDuration, 'f', -1, 64))
        // currentRow = append(currentRow, r.EventPlace)
        // currentRow = append(currentRow, strconv.Itoa(int(r.Priority)))
        // currentRow = append(currentRow, r.Description)
        // currentRow = append(currentRow, widget.NewButton("Delete", func() {}))

        slice = append(slice, currentRow)
    }
    return slice
}

func main() {
    data := getReminderSlice()

    myApp := app.New()
    myWindow := myApp.NewWindow("Table Widget")
    myWindow.Resize(fyne.NewSize(850, 530))

    // Create a table
    list := widget.NewTable(
        func() (int, int) {
            return len(data), len(data[0])
        },
        func() fyne.CanvasObject {
            container := container.NewVBox(widget.NewLabel(""))
            return container
        },
        func(i widget.TableCellID, o fyne.CanvasObject) {
            if i.Col == (len(data[0])-1) && i.Row != 0 {
                // last cell, put in a button
                w := widget.NewButtonWithIcon("Delete", theme.DeleteIcon(),
                    func() {
                        dialog.ShowConfirm("Delete?", "This will delete Event",
                            func(delete bool) {
                                if delete {
                                    fmt.Println("Deleted")

                                }
                                // refresh the reminders table
                                // refreshRemindersTable(db, uimanager)
                            }, myWindow)
                    })
                w.Importance = widget.HighImportance
                o.(*fyne.Container).Objects = []fyne.CanvasObject{
                    w,
                }
            } else {
                o.(*fyne.Container).Objects = []fyne.CanvasObject{
                    widget.NewLabel(data[i.Row][i.Col].(string)),
                }
            }
        })

    // trying to streach up table
    remindersContainer := container.NewBorder(
        nil,
        nil,
        nil,
        nil,
        container.NewAdaptiveGrid(1, list))
    colWidths := []float32{50, 150, 150, 150, 150, 150, 150, 150, 150}
    for i := range colWidths {
        list.SetColumnWidth(i, colWidths[i])
    }

    // tabs

    tabs := container.NewAppTabs(
        container.NewTabItemWithIcon("Reminders", theme.HomeIcon(), remindersContainer),
        // here will be the second tab
        // container.NewTabItemWithIcon("ToDo!", theme.ListIcon(), remindersContainer),
    )

    tabs.SetTabLocation(container.TabLocationLeading)

    // create toolbar

    toolbar := widget.NewToolbar(
        widget.NewToolbarSpacer(),
        widget.NewToolbarAction(theme.DocumentCreateIcon(), func() {
        }),
        widget.NewToolbarAction(theme.ViewRefreshIcon(), func() {}),
        widget.NewToolbarAction(theme.SettingsIcon(), func() {}),
    )

    // Creating finaly looking container
    finalContent := container.NewVBox(toolbar, tabs)
    myWindow.SetContent(finalContent)
    myWindow.ShowAndRun()
}

Depois de montar as partes do contêiner final para NewVBox(toolbar, tabs, table of a content) a tabela ficará pequena. Na posição horizontal não pode esticar bem. No caso de usar apenas tabs com tabela, tudo parece bom.

Eu tentei várias maneiras diferentes de consertar isso, mas não consigo descobrir o que está errado. Quero que o finalContent ocupe todo o espaço livre abaixo.

Espero ter expressado meus pensamentos de forma clara.
