Help on Renderer and Editor

Hi All,
I am new to Swing and get really confused with the concepts of Renderer and Editor. I don' t really understand what Renderer is, why/when use it and how to use it. Similarly questions for Editor. There are a lot of classes related to renderer, such as TableCellRenderer, DefaultCellRenderer etc and they make me crazy. What makes different when we use Renderer and Editor?
Thanks.

Read "Concepts: Editors and Renderers" for JTable at http://java.sun.com/docs/books/tutorial/uiswing/components/table.html#editrender and "Customizing a Tree's Display " for JTree "http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html#display

JTree selection problem when using custom renderer and editor

Hello:
I created a JTree with custom renderer and editor.
The customization makes JCheckBox to be the component
responsible for editing and rendering.
The problem is that when I click on the node with the checkbox
the JTree selection model does not get updated.
Without customizations of the editor and renderer the MouseEvent would be fired and BasicTreeUI$MouseHandler.mousePressed() method would call
the selectPathForEvent() method which would be responsible for updating
the selection model. At the same time if I attach a mouse listener to the JTree (customized) I see the events when clicking on the nodes. It seems like the MouseEvent gets lost and somehow as a result of which the selection model does not get updated.
Am I missing something?
Thanks
Alexander

You probably forgot to call super.getTreeCellRendererComponent(...) at the beginning of your getTreeCellRendererComponent(...) method in your custom renderer.
Or maybe in the getTreeCellEditorComponent(...) of the TreeCellEditor...

JCheckBox as nodes in JTree having problems with custom renderer and editor

Ok, let me give some background. I have an XML document that I am parsing and reading in as a JTree. Works fine.
Next, I have overwritten the DefaultTreeCellEditor to return a JCheckBox and in this implementation of the getTreeCellEditorComponent(), I actually tell the node that he is selected. Works great.
Next, I have overwritten the DefaultTreeCellRenderer to return a JCheckBox and in the implementation of the getTreeCellEditorComponenet, I actually check to see if the Node is selected in the tree based upon the isSelected state of the actual Tree Node set in the tree cell editor, and if so, I set the JCheckBox to selected(true).Works Great.
Now, here is the issue. If a node in the tree is selected that contains children, then I want all of the children of that node to also be selected. However, when I select a node with children only the selected node is changed, and then a few moments later, the system repaints the entire tree and ALL nodes int the tree are set to a selected state. Strange? Yes. Any ideas?? WONDERFUL!! :)
Here is the TreeCellEditor code:
public Component getTreeCellEditorComponent(JTree tree,
Object value,
boolean isSelected,
boolean expanded,
boolean leaf,
int row)
elementCheckBox_ = new JCheckBox();
Component result = null;
System.out.println("isSelected? Editor = " + isSelected);
TreePath newPath = tree.getPathForRow(row);
System.out.println("value = " + value.getClass().toString());
if(value instanceof IMarketTreeNodeElement)
if(isSelected)
if(((IMarketTreeNodeElement)value).isSelected())
((IMarketTreeNodeElement)value).setSelected(false);
else
((IMarketTreeNodeElement)value).setSelected(true);
elementCheckBox_.setSelected(isSelected);
return elementCheckBox_;
Here is the TreeCellRenderer code:
public Component getTreeCellRendererComponent(JTree tree,
Object value,
boolean selected,
boolean expanded,
boolean leaf,
int row,
boolean hasFocus)
Color colSelBorderCol = UIManager.getColor
("Tree.selectionBorderColor");
selBorder_ = BorderFactory.createLineBorder(colSelBorderCol, 1);
normBorder_ = BorderFactory.createEmptyBorder(1,1,1,1);
elementCheckBox_.setText(value.toString());
if(selected)
elementCheckBox_.setSelected(selected);
elementCheckBox_.setForeground(Color.YELLOW);
elementCheckBox_.setBackground(Color.RED);
else
elementCheckBox_.setForeground(tree.getForeground());
elementCheckBox_.setBackground(tree.getBackground());
if (hasFocus)
elementCheckBox_.setBorder(selBorder_);
else
elementCheckBox_.setBorder(normBorder_);
return elementCheckBox_;
Here is the Node Code setting all child nodes to selected:
public void setSelected(boolean selected)
isSelected_ = selected;
if(isSelected_)
if((this.getTagName() == "MARKET") ||
(this.getTagName() == "TIER") &&
(this.getChildCount() != 0))
selectChildren(true);
else
if((this.getTagName() == "MARKET") ||
(this.getTagName() == "TIER") &&
(this.getChildCount() != 0))
selectChildren(false);
public boolean isSelected()
return isSelected_;
public void selectChildren(boolean selected)
int children = getChildCount();
for(int i = 0; i < children; i++)
IMarketTreeNodeElement elem = (IMarketTreeNodeElement)
this.getChildNodes().item(i);
isSelected_ = selected;
Thanks for any help! :-)

I tried to run your sample code and it won't compile. The header files:
#include

do not exist on my install of MeasurementStudio. I am a bit suspicous that I don't have the latest and greatest (loading the dialong resouce gave version warnings). Here is one of my header file headers:
//==============================================================================
// Title : NiAxes3d.h
// Copyright : National Instruments 1999. All Rights Reserved.

//==============================================================================
I
looked on your updates site and don't really see an update that applies to ComponentWorks or MeasurementStudio. My version per the MAX program for 3DControls is 3.5.549.
Do I need a newer version? What do I have to do to get the updated version? What does it cost?

JTable custom cell renderer and editor breaks row sorting

Hello Forum,
I have a JTable on which I set setAutoCreateRowSorter(true); I then hook up a custom cell editor and renderer for the Date class.
this.tblLeden.setDefaultRenderer(Date.class, new DateCellEditor());
this.tblLeden.setDefaultEditor(Date.class, new DateCellEditor());
The sorting for that particular row then breaks, it works fine for every other row. How do I fix this? Just directions where to look would be great too.
Here is my code for the renderer/editor:

Photoshop Help | 3D rendering and saving (Photoshop CS5 Extended)

This question was posted in response to the following article: http://helpx.adobe.com/photoshop/using/3d-rendering-saving-photoshop-extended.html

Sengstack wrote:
I'm aware of the pop-up menus. I don't know that they relate to final, Ray Traced rendering. I think they relate only to Open GL rendering, that is, how the 3D object is displayed in real-time. I think they are more useful as a means to see how the 3D object is built.
The best way to discover what the options do is to try them. I find Points set to "Constant", and Lines set to "Constant", "Flat" and "Bounding Box" will appear in raytraced renderings. There doesn't seem to be an option to anti-alias lines and points, unfortunately.
I also don't know how the CS6 Surface, Lines and Points menus relate to the CS5 Face, Edge or Vertex options.
These menus contain the same items in CS6 as in CS5, plus a few new Surface styles. However, CS6 uses the words Surface, Line and Point instead of their CS5 synonyms Face, Edge and Vertex.
As for the High Quality Threshold option...that applies only to the Ray-Traced render and it is a feature in both CS5 and CS6.
Yes.
What I'm curious about is what happened to Face, Edge, and Vertex. It appears they have been rearanged and put in the Surface, Lines and Points menus but I'm not sure why and what their functionality is (if any) in terms of the final render.
They were renamed possibly because many users will be newcomers to 3D and unfamiliar with the more mathematical terms. Their functionality doesn't seem to have changed from CS5 to CS6. Try them and see.
And I'm wondering what happened to the Render Settings -- Interactive, Ray-Traced Draft, and Ray Traced Final -- and why they were removed (or tucked away in some hard-to-find location) in CS6.
Ray Traced Draft is no more, Interactive is the interactive OpenGL mode where you arrange the scene and/or paint on the models. Ray Traced Final is now simply Render.
Play around with the software to learn what it does.

Problem in JTable Renderer and Editor

Hi All
I have created a JTable with one Column have the Custom TableCellRender, and TableCellEditor
Which has the a JPanel with one lable and a button.
Problem is:
I have to edit the content of table by clicking the button, i will select some data from another dialog,
if i select that data the cell contenet is not updating, and i can not able to select any other cell in the table.
if i resize the colomn the above problem will solve.
Please help on this to fix

Hello,
Very sorry but it is difficult to understand your problem.
Anyway you should have a careful look on Sun's Tutorial for JTable:
http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
Be patient as JTable are complex components.
Good luck, Frank

Table header renderer and editor

Hi,
I am making a customised table, in which the column headers are required to be JButton components.I want to catch action events on the headers.Can anyone suggest how should i go about it?
thanx,
regards.

This isn't as easy as it should be because of how the header is drawn. It doesn't create individual header components, it uses one component like a rubber stamp to draw the headers. So it isn't as simple as just sticking in some buttons in the proper place.
Here is a pretty good example that might get you started:

JTable - help with custom cell renderers and editors

I've got myself into a bit of a mess with cell renderers and editors.
I've got a custom component that wants displaying in a column and then hand over all functionality to this component when you start editing it.
Now how I went out about this was to create a custom cell renderer that extends this component and implements TableCellRenderer.
I then created a table cell editor that extends AbstractCellEditor and implements TableCellEditor and this cell editor creates a new component when it's initialized. I then use setCellEditor(new MyCellEditor()) on the column and setCellRenderer(new MyCellRenderer()).
This works slightly but I'm wondering how this is all implemented.
When I set the cell editor on it's own it seems to be sharing a reference to the single component that's being used which means that if you edit one cell all the cells get changed to the new value.
Thanks for the help,
Alex

only a few forums are actually browsedAnd theSwing forum is one of the most active. Did you search it for editiing examples? I've seen many editing examples posted in a SSCCE format.
SSCEE is also impossible as the functionality spans over about 10 classes We did not ask for your application, we asked for a SSCCE. The whole point of a SSCCE is to simplify the 10 classes into a single class and maybe an inner class for the editor to make sure you haven't made a silly mistake that is hidden because of the complexity of your real application.

HELP: Premiere Pro CC not using all CPU and RAM during rendering and export

Hello,
I am using Premiere Pro CC on a Windows 7. My timeline is quite simple with two videos, one with the movie (mpeg) and the other with the subtitles (avi).
When I render the sequence in PP or export, the rendering time is way too slow and it only uses around 15-20% of the CPU and 3 GB of RAM.
My hardware config is :
- CPU : i7-4770k 3.50Ghz
- RAM : 8 GB
- Disk : 2 x 3 TB SATA (no raid)
RAM is not the bottleneck, neither the disk access.
I have tried rendering and exporting the same project on an iMac (with an i5 2.7 Ghz and 4 GB RAM and only 1 disk) and the result is 4x faster !!!
The CPU usage is close to 100% as well as RAM usage.
So how come PP uses all resources availble on an iMac and not on a Windows 7 ?
Is there any known bug or software bottleneck on Windows 7 ?
My machine is brand new and nothing much installed besides Adobe products.
Any help is very much appreciated.
Thanks,

I just rendered out a a 2 minute sequence with about 100 clips in it and Colorista effects on everything to the Vimeo 1080 H264 preset. It took about 5 minutes to render straight from Premiere, it used all the recourses it could, my CPU was running at near %100, same with my ram and GPU, I was happy.
Then I did another render with Red Giant Denoiser and it now wants to take 30 mins and it is only using about %20 of the recourses available. My problem isn't that its taking longer with Denoiser but that its not using all of my computers CPU and GPU.
Im rendering at maximum render quality and bit dept to H264 (Im happy to wait the extra time), if I try to use VRB 2 it encodes 1 pass at a time and wants to take up to 40 minutes.
I would appreciate some advice on this.

Please help me!--rendering makes the images or video blurry (very pixelated) deteriorates the image Adobe Premier Elements 13 need help! .jpg and mpeg images, but I have never "rendered" before since I got APE 13 about 6 weeks ago. I am desperate for assistance!

That's going to be a ridiculous waste of money and energy.
First of all, the current ATI drivers don't support multiple GPUs, so at the moment even a single 4870X2 would be only a 'normal' 4870 (which is quite a speed beast already). GFX drivers evolve rapidly, so things might look different next month, but when it comes to Linux and hardware there's one Golden Rule: stay away from the newest stuff and wait for proper support to get coded.
I also wonder what power supply could possibly cope with the differences between idle and full load; that's way beyond 400W. But then, I'm one of those "quiet&green" types where >100W idle is already a bit much.
I kind of understand that you want to get it done and not worry about hardware for the next 10 years or so, but that's simply not how the hardware world works and never did. At least not for the average consumer.

Issue regarding Planning layout is not getting rendered and is dumping at : CL_RSDRC_TREX_QUERY_LAYER ~ _GET_PARTPROVS_WITH_TREX_PART in SAP TPM IP

Gurus,
I am facing an issue regarding SAP TPM IP ( HANA)
I have 3 Infoproviders
Planning infocube, Planning DSO1, Planning DSO2 and i created multiprovider and added these 3 infoproviders into it. I have created Aggregation level on multiprovider. Created Bex Input ready query on Aggregation level.
Issue is Planning layout is not getting rendered and is dumping at : CL_RSDRC_TREX_QUERY_LAYER ~ _GET_PARTPROVS_WITH_TREX_PART.
I tried debugging it and found it is trying to read i_r_pro -> n_ts_part. It is populated with only 3 values (i.e. 2DSOs and 1 Cube), whereas <l_partprov>-partprov is referring to Aggergation level, hence read statement isn't successful, it is dumping.
The class CL_RSD_INFOPROV_CACHE->GET() method is trying to populate the N_TS_PART.N_TS_PART uses P_R_INFOPROV table which seems to be already populated. So, I debugged all the below methods to find out how the P_R_INFOPROV but couldn't find any clue.
Can any one help,it would be really help.
Thanks
Ashok

Hello Gregor,
On the launch of planning layout it throws an error message:
Planning is not possible RSCRM_IMP_CORE008.
When I debugged, i got to a point wherein
particular Real Time Planning DSO is
not getting retrieved under the MultiProivder in below class.
Class: CL_RSCRM_IMP_ACTIONS_SERVICE, Method: GET_INFOPROV is not
returning the real time Info-Provider Name(i.e. Planning DSO)
underlyingthe Multiprovider.
I've also tried to run the report mentioned by you for the Multiprovider but issue still exists.
Let me know, if you have any pointers on this topic.
Thanks,

Premiere Pro CC - Playback issues, rendering and export

Hello all -
I am trying to edit, render, and export a video for play on YouTube. The source is a Camtasia Studio 8 Screen capture with a 1080P High Defintion PTZ camera that is hooked up to the computer as the "webcam". We recorded the screen, used Camtasia to produce and edit, and saved it as a .MOV
I then transferred the .MOV to my computer and opened Premiere Pro CC. I have been watching a lot of YouTube videos and have a read a lot of threads, so I decided that a simple edit job would be the easiest and fastest. I have attempted this 3 times now, each try has been a failure.
Attempt 1:
Opened a new project. Imported my video. Dropped it into a sequence. Added an opening and closing title card, plus lower third captions to video, and added transitions. Playback was choppy, so I read that it needed to be rendered. I rendered the sequence (it took most of the evening). When I went to play it back, I just got footage that said "Media pending" in 7 different languages.
Attempt 2: I decided not to render, just export. Followed the steps above, but instead of rendering, and exported it. I exported as media file, chose the TechSmith Capture Codec, and .AVI as the format. Let it do it's thing. The result was very fuzzy, plus the audio was about 10 seconds out of sync from the video.
Attempt 3: I didn't get very far here, because when I started playback to check my audio syncing, my computer started flipping between Premiere and my desktop, just swtiching back and forth.
Any help here, suggestions, would be very much appreciated. I need to post this video for work as soon as I can.

Graphic card help for Pr and Ae use

Hi there great community :)
I'm currently working with only the on-board graphic card, and of course I should upgrade as my GPU is working on 99% on large renders and they are slow...
I've been recommended the GeForce nvidia 2-4GB gtx 760, but neither the 750 or 760 are listed as supported graphic cards in the premiere cc system requirements.
Is there a reason for this or should I ignore that?
Is there a good reason for spending a little extra cash on the 4 GB vs the 2 GB card ?
What exactly will a graphic card do for my performance? (I'm not a computer expert)
My general use is premiere cc and after effects cc
Hope you'll help. Greatly appreciated!
Nice weekend to all :)
- Simon

Premiere accelerates both playback and export with the GPU. AE Ray Tracer acceleration is far more limited and will only be used for a limited functions.

Premiere Pro stops rendering and gives error message when encounters "RGB Color Corrector"

Premiere Pro (and also Encore) stops rendering and gives error message when it encounters a clip containing the "RGB Color Corrector" in any clip. It will process clips without RGBCC, but will stop when it gets to one with RGBCC activavted. PP will render clips if other effects, such as "Fast Color Corrector", "Color Balance (HLS)", and "Three-Way Color Corrector" are selected. However, these do not have the capabilities that The other color correctors will not do what RGB color corrector does, so I need to have this working to finish a large product that is due to the client. Please help me..... I am not using the Creative Cloud version, and can't find either a download for the new update from 2013, or a phone number to talk to anyone.

Using a Win7 computer with 2.8 quad core processor, 24 gig of ram, Nvidia Quadro 5000 video card. Don't think I have any plugins. I looked at one a while back for cleaning up grainy video, but I am not sure I paid for that. Think I deleted it.
Incidentally, someone named Jim on another part of the forum mentioned that this problem has been fixed in the CC version of the program. I am using the non-CC version because I am 68 years old and only do seminars and documentation video. Don't need so many bells and whistles, and definitely don't need learning curves every few weeks. CS6.0.3 works fine for me. By the way, someone else said that maybe version 6.0.1 might work better and I should revert to that. Not sure if it is the version i have on the disk upgrade to 5.5 that I purchased in December.
As it stands now, I have 7.5 hours of a seminar that is ready to go out the door. If there is an upgrade I can get from Adobe, maybe you can tell me about it. If I have a setting incorrect in the video output format, maybe I can change that. So far it just happens with clips in my video that have RGB color correction.
