Anchor not updating after changing button label

Solar2D Widgets
#21

Hi Brent,

So I added the line and the button code looks like this now:

 addScreen.categoryBtn = widget.newButton( { label = "Friend", labelColor = {default={129/255, 202/255, 195/255}, over={1,1,1}}, font = font.robotoM, fontSize = 15, onEvent = functions.openCategory, emboss = false, textOnly = true, x = centerCor.addMainRectX \* 1.375, y = centerCor.addMainRectY \* 1.15, } ) addScreen.categoryBtn.anchorX = 0 addScreen.categoryBtn.anchorChildren = true

But that didn’t work :confused:

Any other suggestions?

Kind regards

Bram

Hi Bram,

Try flipping those two commands: anchor the children first, then set the anchor point. That might do the trick (I haven’t tested it in awhile but I seem to recall so).

That didn’t work either. But the anchor jumps to the correct place after pressing another button, I’ve got a confirm and cancel button. After one of those is tapped the anchor jumps to the correct place for some reason.

#24

Perhaps it’s important to note that the button itself is in another display group. And that other display group is inserted into to the scenegroup.

Hmmm… one more little test: try setting (or rather re-setting) the button’s x and y after you do the anchor commands.

#26

No luck either. I tried to place the code before and after I reset the anchor but no luck.

Hi Bram,

I did some testing and came up with a workaround. Most of this is because you set the button to be “text only” so, internally, it only renders the text object (sorry I didn’t notice this initially).

To make different labels align left, you can use the following workaround instead of setting the anchorX to 0. Just add half the button’s width to an x “edge” position (whatever you need). You’ll need to do this both when the button is created and when the label changes.

[lua]

addScreen.categoryBtn = widget.newButton(

    {

        label = “Friend”,

        labelColor = {default={129/255, 202/255, 195/255}, over={1,1,1}},

        font = font.robotoM,

        fontSize = 15,

        onEvent = functions.openCategory,

        emboss = false,

        textOnly = true,

        x = 0,

        y = centerCor.addMainRectY * 1.15,

    }

)

addScreen.categoryBtn.x = addScreen.categoryBtn.width/2 + centerCor.addMainRectX * 1.375

function functions.categoryItemEvent(event)

    if event.phase == “ended” then

        categorySelector = event.target.id

        addScreen.categoryBtn:setLabel(categorySelector:gsub("^%l", string.upper))

        addScreen.categoryBtn.x = addScreen.categoryBtn.width/2 + centerCor.addMainRectX * 1.375

        print("categorySelector = " … categorySelector)

    end

end

[/lua]

Hope this helps!

Hi Brent,

This did the job. Thank you for your time!

Should I send a bugreport for this or can we just leave it like this?

Kind regards

Hi Bram,

Good to hear it worked! I wouldn’t necessarily qualify this as a “bug” since, if you use non-text-only buttons and the anchor children approach, buttons can be positioned with anchors. But, if you want to file a report anyway to get it on the radar, feel free.
