问题 In this image you can see a default Java Swing color chooser, JColorChooser : What I want is just the color square and vertical slider as outlined in red: I was able to remove all the tabs (Swatches, HSL, etc) and the preview, but I was unable to remove all the sliders. How can I do this? 回答1: OK, just for grins, I decided to create your desired JPanel from scratch, wiring it up in a kind of View-Controller set up, since the model here is trivial -- a Color field within the controller.

Java 7 JColorChooser: Disable Transparency Slider

问题 JDK 7 added a new transparency slider to the JColorChooser: The problem is that I do not want to allow my users to pick transparent colors. Unfortunately, there doesn't seem to be an easy way to disable the slider. One way to get rid of the transparency is to just create a new color based on the selected one but removing the alpha value. However, this gives a false impression to the user as the slider now effectively does nothing and I would hate to have a useless UI element around. So my

问题 I am using a JColorchooser at various places in an application. There can be multiple instances of the panel that can invoke a JColorChooser. The "Swatches" panel in the chooser has an area of "recent" colors , which only persists within each instance of JColorChooser. I would like to (a) have the same "recent" colors in all my choosers in my application, and (b) to save the colors to disk so that these colors survive close and restart of the application. (At least (a) could be solved by

Changing a color chooser button's background color in Java

由 China☆狼群 提交于 2019-11-30 06:01:26
问题 I have a Java button that opens a JColorChooser dialog. I would like for the color of the button to change according to the color selected in the dialog. I have tried calling the setBackgroundColor() method of the button, but in my case it has no effect (the button is on a JToolBar in Winsows 7). Also, this question suggests that changing a button's background is not platform independent. Maybe the answer to this problem is not to use a button in the first place. So, my question is: is there
