Missing how to interact, how to CURD

Is it possible to construct a solution with the existing API?

No response

Describe the solution you'd like to see.

It should be added to the operation item, CURD and other interactions

[SKBotNL]

It's supposed to be like that, it's a demo. If you want to know more about tables go to the documentation

[SKBotNL]

What doesn't work/what error do you get?

[Jacalz]

Please @junmaqiang, use a discussion for questions. This is an issue tracker and intended for reporting bugs and feature requests. I will convert this for you but please use https://github.com/fyne-io/fyne/discussions for questions next time.

I suppose you mean CRUD? If you need to remove or delete items just make sure that the Length function (the first passed to NewTable) returns the length of a data source instead of hard-coding it to numbers like in the example above. Then you can just remove the item from the slice and call .Refresh() on the table.

Ok, thanks for the reminder.

My question is to know how to pass parameters to the method of the component?

[junmaqiang]

f.OnActivated = getInfoa(id.Row) // My wording is incorrect

[Jacalz]

You cannot set the value of the OnActivated field to the return value of a function that doesn't return anything. If you want to give it a function then you need to pass the function itself and not call it (i.e. set it to the name of the function).

However,I assume you want to do this instead (the types of functions are different):

f.OnActivated = func() {
    getInfoa(id.Row)
}

hey, i think you can take a look at this, and i will also provide you with the working code.

Maybe you want the OnSelected field? If you set that to a func of your code it will pass the id that is being selected.

[junmaqiang]

yes, i want selected id.Row

[andydotxyz]

The demo you pointed at as lacking this behaviour absolutely does have that code:

fyne/cmd/fyne_demo/main.go

Line 222 in 8c25095

OnSelected: func(uid string) {

.

[junmaqiang]

type ToolbarAction struct {
	Icon        fyne.Resource
	OnActivated func() `json:"-"`
}

how do I pass parameters to the method OnActivated

[Jacalz]

how do I pass parameters to the method OnActivated

#3572 (reply in thread)

[junmaqiang]

This problem is solved

				icon.Items[1].(*widget.ToolbarAction).OnActivated = func() {
					fmt.Println("AA", id.Row)
				}

[andydotxyz]

I just wanted to mention that putting a Toolbar inside a table seems strange. You would normally have only 1 toolbar, and you can place it above table with container.NewBorder(...).

[junmaqiang]

Used as a button, because there are icons and events

[Jacalz]

What is wrong with using a button? You can set .Importance = widget.LowImportance for it and also set an icon.

[junmaqiang]

I'm going to try it later

[junmaqiang]

fyne's table has no header which is very bad
