Can I resize undecorated JDialog with mouse?
Hi all,
I use a undecorated JDialog as a message panel in my application, but I can't resize it with my mouse. Can this be achieved?
It's not like Photoshop resizing at all - Flash is a vector
engine, not a
bitmap engine. Depending on the image and how much you are
scaling it, it
can look OK scaled, but it'll never be as good as in Pshop.

InDesign CC 2014 can no longer drag objects with mouse
I have been using InDesign for months with no problems but suddenly I am having mouse issues. I can use my mouse to resize objects and make selections but dragging objects in the document or in panels (for example, reordering spreads) no longer works. I am using a mac on the latest 2014 CC release of InDesign, and have tried all the usual tricks (Ctrl + Alt + Shift + Cmd on startup to remove preferences, manually deleting preferences (both files), reloading software, rebooting machine, reinstalling InDesign) but the only thing that works is rebooting the machine.
However, within 20-30 minutes after a reboot, the problem returns out of nowhere. I don't use plugins with InDesign and haven't changed hardware or software recently so I have no idea what's causing this.
Does anyone have any info that might help me out? From googling around, it seems most people have solved their problems after a preferences dump, but mine keeps on coming back!I've actually been discussing this problem in another thread but this one is dedicated to it.
This cropped up for me prior to the New Year and I've found no solution. I actually did what Steve Werner suggested this week and created a new OS X account. But the problem cropped up in the new account today.
I don't know if this is a common or not. I'm part of a large creative team and as far as I know, I'm the only user experiencing this. I've trashed preferences, uninstalled and reinstalled InDesign, restarted the computer, etc. Nothing works. -
Why can I now highlight text with mouse pointer in Adobe Reader 9
I just downloaded Adobe Reader X. I think I prefer Reader 9. I don't like being able to click in the document and have a flashing place mark (right terminology?) there. This is now happening in the Reader 9 version too, and I can copy text this way, but I don't want this. I didn't change any preferences. Can anyone help?
Like I said, I didn't change any of the preferences, so I don't know why this happened. I think it only happened after I opened Adobe Reader X. I see no options in preferences for turning on or off the ability to highlight text with your mouse pointer, and I thought you were not supposed to be able to do this in Adobe Reader 9.

Pages '09: Can't select multiple objects with mouse?
Hello! I want to select some shapes. I know that I can hold down shift and click on them individually one by one, but they're very many and grouped together, so I just want to draw a 'selection-rectangle' with the mouse, just as it works in all other programs I've ever used. But this doesn't seem to work. What am I doing wrong?
Hello Stef,
You can simply click and drag over an area to select multiple objects if you are in a Page Layout document, but since this is your fourth post you may be new to Pages and you may not yet even be aware of the Page Layout mode. At the top of your Pages window is the document title and next to the title in parentheses are the words "Word Processing" or "Page Layout".
So, in a Word Processing document, it's just a little bit more involved. In the upper left corner of the window, click on the View icon and select "Show Layout". You will see gray around the edges - your desktop, a white sheet - your paper, and three rectangular outlines - the header field, the text frame and the footer field. This assumes that you have the Header and Footer turned on.
As you move your mouse, the text insertion bar, a vertical line with curved features top and bottom, will move about the document. Move the insertion bar to the margin, outside of the boxes, and press and hold the COMMAND key. Your cursor will change to an arrowhead. Now you can select multiple objects by click-dragging, just as you are accustomed to doing in other applications.
Regards,
Jerry -
I can't resize new rectangles with the new Illustrator 2014
I know from reading other boards that there are related issues with snapping to grid but I'm having an issue only with resizing rectangles when I create them new. We have others in our company using Creative Cloud that have updated and they are not having the same issue I am having.
Basically when I create any new rectangle, or rounded corner rectangle it is a fixed size and I am not given the handles to resize it. I have to select the object then go to Object > Shape > Expand Rectangle in order to get the corners to grab and reshape or resize. I have checked and unchecked all of the settings that I can see or read about and nothing changes this. It's a real pain to have to go through this with every object I create.
I have also tried rebooting the software and my computer several times but it's still the same.
Am I just missing some small setting somewhere? -
Can't select desktop items with mouse...
Good day,
I am having an issue with a G4 Quicksilver workstation at my office that is running OS 10.4.10. it seems that i can not use my mouse to select any items on my desktop. i can tab through all of the items, and my mouse is able to work the menus fine, but i cannot open or even select anything that is on the desktop, including my dock. has anyone else ever heard of such a problem, and if so, is there a simple fix for it?
thanks in advance,
crHi Chris,
Try reinstalling the drivers that came with the mouse.

Can't scroll between photos with mouse anymore?
I am just beginning to use iPhoto 08, and have noticed that now when I am viewing one of my photos, there are no arrows to move on to the next (or previous) photo as there was in iPhoto 06. Also, I remember there used to be a bar of images across the top of the screen so that if I was viewing one photo and wanted to move on to the next one without exiting back to the menu, I could just click that photo.
Has this functionality been removed with iPhoto 08? Is the only way to scroll between photos (when they're being viewed in the window) to use the keyboard arrow keys? Or to exit out of the picture view and back to the main menu of pictures?hiddenmuse
Here's the difference:
When you double clicked on a pick in v6 it brought you to edit view: A strip of pics across the top and the right/left arrows lower right, all in the main window.
To do this in v7 click on the edit button.
Or: iPhoto -> Preferences -> General -> Double click photo: and select 'Edits Photo'

The problem is that when a resize that needs a setLocation() to go with it, the frame flash/flicker a lot. I already tried to set "sun.awt.noerasebackground" to "true" but it didn't help me. Is there another way to solve the flickering problem?
I notice on normal frames, there is an outline drawn as the mouse moves around, then the windows resize/setLocation at mouse release events. How can I do this (if the flash/flicker problem can't be solved)?
Thank you very much for your time!!
Cheers!Thanks for the reply! But I don't have a problem with moving the undecorated JDialog. It's the resize operations that I try to do. If the resize operations need to resize and setLocation (i.e NW, SW, NE, W, N resize) then my JDialog will flash... I doubt that you need to read it... If you are familiar with this kind of things then once you compile and run it, you will probably know the fix right away...

Ae 13.1can't pan in viewer with mouse wheel button !!!!!!
one of the bad things in ae 13.1 is that you can't pan in viewer with mouse wheel button
In all honesty though, even if fixing this kind of bug would create a new one, its not a bug that should be ignored. Its a major one imo (fix this bug and create a new one, I would personally take my chances). I remember after effects had a bug in a recent update, were audio always was set to low quality when you export, which was very annoying, and it wasn't fixed for months! This bug is worse, and happily I read this thread before updating so Im staying away for now, I hope it won't take months to fix this one.
It makes sense and Im really happy to hear a chunk of the AE team is working on optimizing the code.Though I think they should devote more people to that. AE is such an old program that I assume those working with keying or other of the features that have been updated lately, they bought a better plugin for it allready. I would much rather have NO updates for a year if that means the program would become more stable, faster and in the future they would not need to patch up layers and layers of old code, as you say....and from what I remember the response from the community was pretty much the same from every single one when it was asked in public what people wanted in the future updates....a faster program. THe content of AE is all ready great, and you can get plugins for pretty much everything you need...except optimization and an up to date software that uses the computer to the maximum potential. -
Tabcontrol transitions between tab with mouse gesture ?
Hi
Can we create a tabcontrol with gridview in tab, and when we can scroll gridview and tabcontrol with mouse hold and move ?
Example :
Tab1 Tab2
1 2 5 6
3 4 7 8
When we hold and move mouse Up-Down gridview will scroll in tab.
When we hold and move mouse Left-Right we will see tab transtion
Tab1 Tab2
.. 2 5 ..
.. 4 6 ..
Tab navigation will dependent where we release mouse.
Exactly i want do something the same app screen smart phone, exclude it can scroll in Up-Down in a page.
I'm researching in Google but now see anything sample like this.
Please help me.
Sorry for my bad english.Hi Cygnus
Durant
I'm not really what you said.
We will create
<TabPanel >
<ScrollViewer>
<StackPanel >
<Item>
So will
horizontal smooth-scroll we will use ScrollViewer
Add handlers for MouseMove to
scroll verically in StackPanel ?
Sorry i'm just beginner. -

How do i run an external monitor with my macbook and change settings so that when i close the lid the signal to the monitor is not lost and i can continue using the mac with a mouse and a wireless keyboard?
No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.
