I'm trying to create a simple Border layout template and I'm using frame.pack() to determine frame size. I have an invisible label in the centre region and the pack method doesn't seem to be taking the label into account so it doesn't show. I know it does work initially because the frame is initially the right size for the other components.
So how can I get the frame to take the invisible label into account? The label is only visible when the button in the centre region is selected.
Everything works, apart from you have to manually increase the frame size to see the label.
I think that it depends on the layout manager of the container containing the label. Some layout managers compute the preferred size based on the visible components only, and others take invisible components into consideration. GroupLayout, for example, has the setHonorsVisibility method.
Anyway, the easiest way is probably to make the label invisible after having called pack.

I am having an app, which uses the Forge API. The UI displayed when pushing the Forge button "Settings" in "settingsTools group", overlaps one of my buttons.
However since my app zIndex is set (I am in react code) the click upon close of the setting UI, triggers my buttons instead of the close button.
Hence, I am intrested in setting the "Settings UI" to front so the click upon the close button triggers close. My front end code is in the react framework hence a simple zIndex parameter to set could do the trick.
How can I do so?
Instead of playing with hacky ways, consider using the docking panels provided by Forge Viewer. From my understanding, it can also work with React.
To elaborate the usefulness of panels, consider the following example:
Here I have a floating div, showing me some information related to the model. Obviously I've set a high z-index, to bring it upfront and here I have the same problem as you have - when opening things like settings, properties, model tree, etc, they all appear behind my div. Moreover, when changing the size of the window, I have to deal with my div position.
On the other hand, Forge Viewer uses everywhere panels, like this very Settings dialog.
Thus, if you would place your button into this kind of panel, this would save you from headache with z-index, docking, rescaling etc, as all the panels are working nice one with each other, as the below Robot Control Panel:

I'm building an access database for my music catalog. I've created one main table with a bunch of queries. I want to make a decent looking front end. I have a bunch of buttons with macros assigned to them already. The problem (which I presume is something very small that I'm missing) is that I added a picture to the button it's just a picture of vinyls that would run a query to show my vinyls. The picture only displays a portion rather than the whole picture. I can get it to show the picture by expanding the button size but this is not desired.
Any help is appreciated.
Thank you and Happy Thanksgiving.
The button doesn't resize the image you assign to it.
You first need to resize your picture files to whatever size you deem suitable for the button, then use that scaled down image.
Alternatively, you can use the Image control instead of a button. That control will allow you to resize the image inside it, but it will generally appear slightly blurry, depending on the image and the dimensions you resize it to.
Also, forcing Access to load larger image and then resize them can make your application less responsive if you have a lot of images, since you make it do extra work.
A workaround is to work with an image and a button.
Insert and size the image you need in the form
Add a button, setting its property "transparent" to true
Overlay the transparent buton over the image
Make sure the button is on the topmost layer usuing the "bring forward" in the image menu. We have then the transparent button over the picture
Associate VBA code or macro to transparent button.
For all intent and purposes, user will click on an image, but because there is a transparent button over it, will be in fact clicking on the button
I need one of my gwt Panels to be always above all other content and always accessible for user to click on it's elements.
Even if there is a DialogBox opened on page my Panel should flow over it. How can I achive this?
With a PopupPanel you should be able to set the z-index CSS property to a large-ish number that will place it in front of any other floating panels (including DialogBox)
popupPanel.getElement().getStyle().setZIndex(100);
I have a control in which I repeatedly run some animations (e.g. DoubleAnimation). Can I detect if my control is no longer visible to the user? E.g it gets scrolled away from, the user navigates forward to another page, or it gets obscured behind other controls.
I don't want to run those animations unless at least some part of my control is visible for the user.
You could analyze the visual tree or get a transform from control coordinates to screen coordinates to see if its positioning is within the view port and also check things like opacities, visibilities etc. of controls down the visual tree path, but that is so processing intensive that it is not worth doing all the time for a general solution.
The only thing that would make sense is to handle the ScrollViewer.ViewChanged event and check if the offsets make it visible or not while limiting the TransformToVisual or VisualTreeHelper calls only to times when the actual layout within your ScrollViewer changes.
I have a dialog box with a bunch of dimensions that a user can change by moving/dragging, including a JTable with resizable/draggable columns.
What I would like to do is to make the state of these resizable columns / dialog boxes / etc. persistent, so the next time my application starts up, the user doesn't have to go through the resizing step all over again.
What's the most convenient way to do this?
You should probably take a look at the code in (the now probably dead) JSR-296. A part of it was focused on persistent session state, and I know for sure that the code for persisting window locations and such was already functional and in the basic framework. It should either already do what you want, or provide a good starting point.
