Created attachment 229045 [details] Pure SWT Snippet showing CoolItem working on Windows I raise this bugzilla about a specific Windows issue, exists on Windows 8/7/XP, the chevron of the CoolItem is not displayed on windows. See http://www.eclipse.org/forums/index.php/t/462978/ for all details. I have seen that even on Linux the chevron for the CoolItems of the main toolBar of Eclipse does not appears with Eclipse 4.3 M5a
Created attachment 229046 [details] SWT/JFace Snippet showing CoolItem not working on Windows I have attached 2 code snipperts : - one in pure SWT code showing that a chevron is displayed to access hidden buttons on Windows - one in SWT + JFace ToolBarManager/CoolBarManager code showing that it does not works on Windows.
On windows to fix the issue of not displayed chevron on Snippet140Bis.java example, I add the following lines after line 42 : ToolBarContributionItem toolBarContributionItem = (ToolBarContributionItem) coolBarManager.getItems()[0]; toolBarContributionItem.setMinimumItemsToShow(1); with that the ToolBarContributionItem will compute a width for the minimumSize lower than by default. Now to have the chevron display on windows for the main coolBar of Eclipse we can add the following lines at the end of CoolBarManager.itemAdded() method : if(item instanceof ToolBarContributionItem){ ToolBarContributionItem toolBarContributionItem = ToolBarContributionItem)item; toolBarContributionItem.setMinimumItemsToShow(1); } But this remains a work-around. And there is yet a bug, for example on the main toolBar of Eclipse, on resize of the window the chevron appears/disappears if yes or not it remains enough place to display all actions, but on selection change when the set of actions to display changes the chevron disappears while it should be visible because there is actions not visible. Could I have feedback of someone from jface or swt to help me in my analysis, especially of this last bug? Best Regards.
Can you identify a particular eclipse version that this works correctly in ? Is it specific to a particular version of Windows (i.e. Does it work on XP but not Win 7...) ?
This issue has been identied on Windows XP/7/8 and with Eclipse 3.6.2. On my Windows 8, I have just tested with Eclipse 3.3 and the main toolbar does not show chevron.
Created attachment 229899 [details] A snippet code of CoolBarManager with dynamic changes of visible actions I have attached a new release of the initial Snippet140.java to have a CoolBar managed by a CoolBarManager, whose visible actions changes when the user click on actions B8 or B9. If at the beginning the user has decreased the width of the windows to have chevron displayed, now the user click on B8 action to have less visible actions and the chevron disappears, it's ok. Now the user click on B9 action to reset visible all actions which has the effect to display the chevron to show hidden actions. This jface/swt snippet show the correct behavior which should have also in the Eclipse main toolbar but it is not the case.
