I am working on java and i want to make my java GUI display data like this.
What component or what layout should i use?
First, i think i should do something with JTable to display the table like this.
Second, in each day in this calendar it is clickable. and I think I'll use JButton.I'm not sure if it's ok.
third, the most top of the calendar, i have no idea how to make it display like that.

I'm trying to decide on the best way to display a timetable to the user.
Ideally I wanted the data to be displayed in a table layout but I quickly realized that each table row required like 18 text views for the relevant data.
I've checked a calendar component, no use. A table layout does seem the best way to go but what's the best way to implement it so that it's easy to get data from my DB and read it into the table?
You can use GridView with its adapter:

I'm working on creating a basic user interface and I wanted to try and create a portion that is in a scrollTaskPane and is capable of holding multiple entries. As I'm going about creating it I can obviously test it with a simple amount of entries but I'm confused how I can go about later allowing for it to take input to create entries in the scrollTaskPane of maybe 1 entry one time, and then later needing to allow for input of 20 entries. I only know how to use absolute positioning and am trying to figure out the best way to go about it. I also need to later be able to select each entry.
For the entries that will eventually be called and displayed in my interface, I'm planning to store them in a simple text file and use a semicolon as a delimiter between the task "Type" "Name" "Description"(which will be accessible through a button) and "Due Date". Or I may try to learn to use a database for the information. But I haven't decided yet and don't know anything about connecting a database with a java program.
This is the current look (the scrollTaskPane in the middle). And my goal is to put in entries that are each rectangle boxes going across the scrollTaskPane with a checkbox on the end of them. Should I use some sort of grid layout? Or something else? I'm a beginner at user interfaces, so any help is appreciated!
You can make a custom layout, and then keep adding those layout. So extend a layout class, add TextField and a check box in the layout. Initialize the layout with your values, add then add to the ScrollTaskPane.
Hello im making a program and using TableModel. I have 6 column filed with string's. I want the sixth column string make it look like URL. When i mean look like URL , i mean turn it into blue and be underlined. Is it possible to do that?
You need to write custom TableCellRenderer for your jtable. See this link.This may be helpful for you.
Sun had a very good tutorial (http://docs.oracle.com/javase/tutorial/uiswing/components/table.html#modelchange) on cerating jtable. just go through it before you start. hope this tutorial will help you.
But below is my suggestion.
("<html><b><u>link</u></html>");
<html><b>bold</b></html>
a similar kind of thing
However, I wouldn't recommend altering the data in your model just to effect display. Instead I would create a custom cell renderer which accomplishes this effect and set it on the table. You could either wrap your text in the HTML or manually set font color and style properties on the renderer to mimic html.
Now even if you were to include the url in the html you still can't click on it. There is no component in the table. You don't really want to go into edit mode when clicking on a url. You just want to open that link. To accomplish this you would add a mouse listener to the table itself. When you receive a click event, you would then programatically determine which cell it was over, go back to your model and get the url, and finally use other Java API calls to open that url.
I'm pretty sure you can simply create a string containing
<html>...</html>
and it will work. Just code your link inside the html tags as you would in html. You'll just have to add extra code if you want it to appear blue. I think:
<font color='blue'>
would do it
Hey i want to create a thumbnail viewer, for my app, i want something similar to this.
I was wondering if there is a pre-existing component that can display thumbnails (FREE), or i was considering to use a JTable, with a custom cell renderer.
What do you think, what would be the best way.
It will be used to display images, keep in mind that i must be able to select individual and multiple files to perform actions on them.
thx in advance.
A JList would probably be better than a JTable. You can use a "horizontal wrap" style. You can always create a custom renderer for the list as well.
My current application uses a JList and everything is well (the only customization I did was to set the italic font on some of the rows).
Now I want to "upgrade" the user interface and instead of just labels in the List, I want a checkbox and a text field to be able to update the entry.
I started changing the code and adding a custom cell renderer and a custom cell model. My current problem is that the JPanel that the cell renderer is returning is not using the whole width of the container, so several list items are actually shown on the same line.
But now, I am wondering whether I should just change the whole thing to use JTable. I still need to add / remove items in the list though...
Any suggestion which one is better ? and if going with the JList, how should I go about fixing my current problem ?
In my experience using JTable is usually easier as it allows more complex data and functionality out-of-the-box. Usually when I try to do something the JList can't do, I just switch to JTable without a second thought. What you want sounds like something that should be pretty trivial to implement in a table. I suggest you try it out with some mock data to see if you can make it look and work the way you like (especially in case you want it to look like a list).
Try calling setLayoutOrientation(JList.VERTICAL) on your JList. That will restrict JList to a single column.
