However, using the built-in virtual keyboard might still be a better approach than trying to create your own. The built-in keyboard doesn't have an officially supported and documented public API and is not guaranteed to be maintained between Java versions. JavaFX already has a built-in virtual keyboard.

The code for the color chooser is not FXML based, nor does it directly implement a keyboard which is what you want, but it does demonstrate automated sizing of buttons as you asking about in your question.Ĭonsider using the JavaFX virtual keyboard The color choose implementation is based on a resizable grid of resizable buttons, so as your change the area available for color chooser grid, both the grid and the buttons in the grid expand or contract. If you wish to continue trying to create your own implementation, this sample color chooser might be of assistance. To better understand layout management in JavaFX, I recommend viewing a past JavaOne Interface Layout with JavaFX 2.0 presentation. Make sure the resizable parent is actually resized (something like a StackPane will be automatically resized to fill available area, I don't use AnchorPane very much so I'm unfamiliar with its resizing behaviour).If you want additional padding in a button, you can use -fx-padding in CSS or tPadding(new Insets(.)) in code.As you are doing an onscreen keyboard, one way to achieve this is to increase or decrease the font size, then the button will size itself automatically. Get the preferred size of the button to be size you want.This is required because the default constraint for a button is that its maximum size is its preferred size, so it doesn't automatically grow to fill available space. Remove the maxSize constraint from the button, tMaxSize(Double.MAX_VALUE, Double.MAX_VALUE).If you make the font size larger, the buttons will automatically change their preferred size to match this larger size, plus all of the text will be automatically rendered and fit within the preferred size and be displayed in the suggested padding layout for that font size (which is probably what you want).īasically the rules to get a button resizable are: I want to make buttons like Ctrl smaller without losing the text.įor your particular case, rather than trying to resize buttons using padding or additional layout constraints, try adjusting the font size ( -fx-font-size) used for the parent layout container for your virtual keyboard.

Turning on Hgrow and Vgrow didn't work.Īnd I can't find how to set the padding on buttons.
I want the buttons to gain/lose size until it fits the window. īut when the window is resized, the contents don't. I'm using the Scene Builder to make the FXML file. I'm trying to make an on screen keyboard with Javafx for the layout.
