Hi,

in my application, several panels exist. Their size is fixed and can not be changed by the user, but they can be minimized and restored by the user. It would be nice to have the possibility to programmatically react to these MINIMIZE and RESTORE events. Right now, I have to poll the panel zoom attribute.

Thanks!

In a Tree Control you can change the size of cell font and, as a consequence, the size of the cell itself.

But the size of item images and plus/minus boxes is fixed: in this way you can have items with large fonts near small images and plus/minus boxes (see attched).

I think that this is quite ugly to see...

I think that images size can take some discrete values (16x16, 32x32, 48x48 and up to 128x128 for example), so that the larger one (smaller than the cell height) is automatically used.

I suggest a similar behaviour also for plus/minus boxes

If you select an User Interface control you can move it to a new location in two ways:

1. through Arrange >> Control Coordinates you can set the new (X, Y) position
2. moving it of a predefined offset every time you press one of the keyboard arrows, or of one pixel (SHIFT + arrow)

Using the arrows is an easy way if you want to move the control of a little quantity, but it's difficult if you need for example 200 or more pixels.

Moreover with Arrange >> Control Coordinates you can set the new location for a group of selected controls using the "All" buttons.

But if you want to move a group of controls of a desired offset you can only use the arrows.

I suggest the implementation of specifying either an absolute position or an offset throug the Control Coordinates window, both for a single control and for a group of them.

Panels and controls scrollbars have fixed size (height for horizontal ones, and width for vertical ones) that can't be changed and doesn't reflect the Operating System setting (see attachment).

For tree control, for example, there is the option "Small/Medium/Large" but this isn't enough if you're designing an user interface for a touch screen panel, where you must drag scrollbars with your finger.

The custom scrollbars are built over a graph control, and are quite ugly, compared to the Visual Studio style...

I think a fully settable scrollbar size would be a great improvement...

I use SavePanelState and RecallPanelState all the time but it give me error when I add/change existing control. I would like to request save and recall only one control that way I don't have to worry about other controls which I am not interested in.
