Summary | 0001743: skychart does not respond to any input. | ||||
Description | This has happened to me once before and i don't know what event causes it. I was just playing around with the chart. The program does not respond to any mouse input. clicking on any of the tools does nothing. Clicking on a menu will drop the menu down, but it does nothing further. For example click on Observatory in the setup menu does nothing. The observatory dialog does not open. Switching away from skychart and then click on it again does redraw the menu. But that is all it does. The cursor also changes back to the target icon, from the mouse pointer. But nothing else. Right click does nothing on an object. The keyboard arrow keys more the chart contents to a different part of the sky. It redraws the chart. The keyboard shortcuts do nothing. If I click off the skychart and then click back to the chart at some location then it does update the chart coordinates at the bottom left of the display. But if I click again in some other spot it does nothing, until I leave the skychart window and and click off screen and then come back and click on it. The menu updates when I do that also. It is idle. It is not using any CPU time I checked that with Activity monitor. It has 4 threads. Using 308 MB. The Quit skychart menu item is disabled. Command Q does nothing. The Doc Icon for skychart pops up and the Quit is enabled. I clicked on the Quit and the skychart dialog asking me if I want to save the settings came up. I responded yes and it quit. I tried resizing the window. That did not work. | ||||
Steps To Reproduce | I have no Idea. Just playing around with it, looking at different parts of the sky. | ||||

Perhaps there is "View -> Calendar" form stayed open and focus is changed to main form, then open any non-modal form (e.g. Observatory) and then change focus back to main form - application will become totally or partially unresponsive. This is the way Lazarus handle this situation, when at least one non-modal and one modal form is open, however that is not correct way to do. Correct way is that last open modal form stay on top of open application and do not allow to be changed focus on any other related, before that modal is closed. If unresponsive situation happens, try to see is there any application related form left open in behind and then close it first. Only few non-modal forms I'm aware in skychart: telescope RA/DEC view, Calendar and "Solar System Information" which can be open all the time. |
|
This is maybe related to this two issues : 0001642 and 0001696 The two cases are fixed in version 4.0 but maybe I miss another one, look if the problem is after opening some dialog. The problem is when a modal form is opened from a modal form. This is specific to the Mac version and probably related to the qt4/cocoa interface. Sasa, I not understand what you meant, in Linux the Observatory dialog is really modal and you cannot focus the main form when it is open. And non-modal form like the Calendar cannot lock the main application. |
|
I read the comments about double showmodal form in 1642. Mentioning the Observatory triggered my memory as to my changing the observatory site. Changed from Palomar to Home. I tried that again today and it hung the exact same way as it did before. So it sounds like a known problem that will be fixed in 4.2. You don't have to use Force Quit. Just right click on the Doc Icon and click on the "Quit" option and it will terminate normal asking you if you want to save the settings. |
|
Patrick, If you open non-modal form (e.g. Calendar) and then modal (Observatory), you are allowed by current Lazarus (1.6.x) to focus on main form. In that case, nothing on main form will respond. That is how behaves in Linux (probably in Windows and Mac as well) and it is bug in Lazarus. I have attached very simple example. 1. Click on first button to open non-modal form 2. Click on second button to open modal form 3. Focus main form - it is allowed, however then nothing in main form is responsive. 4. Close then modal form and everything back to normal |
|
That is not how it works on my Mac when I try it. 1. Click on first button to open non-modal form. (Calendar...) a. dialog opens. b. can't change focus to main window. c. all menu items are greyed out so I can't select them Therefore I can't do steps 2-4 See image modal issue.png That's as it should work by my thinking. |
|
Oh, you mean using the Toolbox item calendar. Sorry, still learning. But that is pretty normal. That would be expected. I don't see the issue here. |
|
Rolf, 1. Open from main menu: View -> Calendar. Or click tool bar icon "Ephemeris calendar" 2. Open from main menu: Setup -> Observatory. Or click on left tool bar icon "Observatory" Can you focus on main windows and zoom in, search any object or anything else? |
|
I can open the "Ephemeris calendar" the window displays on top of the main window. If I click main window the "Ephemeris calendar" moves to background. I click on "Setup Observatory". The observatory dialog opens on top of the main window, covering part of it. The calendar is behind. I can move the main window and see both of the other windows. But the calendar will always stay behind while the Observatory window is open. I cannot focus on the main Window or do anything with it as long as the Observatory window is open. Once I close it I can access the main window and the calendar window. All is as it should be. see calobschrt.png That all looks pretty normal to me. |
|
Thank you. I think all is quite clear now. |
|
Normally you can not do anything on other skychart window when the observatory setup is open. But you can do it now on the Mac because the setup forms are not modal because of bug 0001642 caused by a Qt4 bug. As a temporary fix, waiting for Qt5 version, I replace the modal setup by a simple "on top". Source code change is here: https://sourceforge.net/p/skychart/code/3516/ Linux and Windows version are not affected by this change. Sasa, I tested your test_focus on different system and repeat with skychart. I can reproduce the problem only on my Lubuntu 16.04 laptop. On Kubuntu 16.04 and 17.04 (with kde5), Fedora 26 (with gnome3) or Windows 10 it work normally, you cannot focus or do anything in the main form when the non-modal and the modal form are open and it is not possible to hide the modal form in any way. So this bug is probably with the openbox window manager in ubuntu 16.04. |
|
Patrick, Yes, I have currently Lubuntu 17.04 where this is tested. In any event, this is not related with this issue I though it is, nor with skychart at end. Sorry for pollution. You may move or delete all unrelated notes and test archive. |
|
Maybe the problem with Lubuntu need it's own issue to help other with this problem. Rolf, about the original issue. The next time you get the problem can you right click on the skychart dock icon and select "Show All Windows" to be sure there is not something locked in the background. |
|
The dock icon when selection "Show All Windows" only shows one window. I can repeat the issues at will. I don't know how to edit the "Steps to reproduce the problem" or I would but it in there. This works every time: 1. start CdC 2. click on: Setup->Observatories... 3. click on: Observatory database 4. click in Observatory database dialog: OK (dialog closes) 5. click on Observatory dialog: OK (dialog closes) 6. click on main window, NO RESPONSE to click, mouse does move around. 7. on Dock icon right click then click on: Show All Windows ( only the main window shows) 8. on Dock icon right click then click on: Quit 9. Save configuration now dialog opens up: click Abort/No/Yes as appropriate. Cdc ends Note: step 7 is done only to show that no other windows are open. Steps 8-9 show how to end CdC without a Force Quit. |
|
Thank you for this detailed steps. Now I can reproduce the problem with my Sierra VM. Strangely the problem is not present with the Yosemite VM. |
|
My OS-X Laptop is on 10.8.5 (Mountain Lion) and CdC does the same thing there as described above. |
|
Maybe the difference is because my Yosemite hold the development environment? Anyway this is fixed by revision 3627: https://sourceforge.net/p/skychart/code/3627/ and available in today beta skychart-4.1-3627-x86_64-macosx.dmg Please reopen this issue if you find another case. |
