I create a Text Layer with this code:

ImageEnView1.LayersAdd(DateTimeToStr(Now), Self.Font.Size, Self.Font.Color, Self.Font.Name);
TIETextLayer(ImageEnView1.CurrentLayer).SizeToText();




However, when I try to ROTATE the Text Layer with the Rotation Grip, I get this:



So how can I rotate the LAYER instead of the text content with the Rotation Grip?

Hi Peter

For all non-image layers, only the content is rotated.

If you set:
TIETextLayer(ImageEnView1.CurrentLayer).AutoSize := True;


Then you will get a better result when rotating.

Hi Nigel

Thanks for the valuable hint.

Alternatively, how can I hide the Rotation Grip only for this Layer - without having to generally exclude loShowRotationGrip from LayerOptions?

Hi Peter

I'm afraid there is not an option for that. You might be able to toggle loShowRotationGrip on layer change.

Hi Nigel,

Wouldn't it be helpful implementing the properties ShowLayerRotationGrip: Boolean and ShowLayerResizeHandles: Boolean as inherent TIELayer Read/Write class properties?

Hi Peter

Each layer's grips will be hidden if TIELayer.Locked is enabled for that layer. At this time there is not a way to disable per layer rotation. We will consider that for a future version.

Hi Nigel

If TIELayer.Locked is enabled for that layer the Layer cannot be moved or show its border, as the Documentation says. But what if the user needs to move the layer while not being able to resize or rotate the Layer?

Hi

On layer selection you should toggle the MouseInteractionLayers values of miMoveLayers, miResizeLayers and/or miRotateLayers
