Drop through right click on LabVIEW Tree

I have a LabVIEW Tree control on my front panel and I would like to allow the user to select an item on the tree with a right click. I believe it's called right click drop through, but I can't find any information on it. Is it possible to do this?

One way to do this would be to use the Tree:Mouse Down? filter event case. Wire a '1' constant to the Button Output Data Node and all clicks will be treated as a left-click.

Context Menu on the right click of af:tree node

Hi Experts,
I am using drag and drop functionality in af:tree.In that i used one tree for drag source and another one tree for drop target,and it is working as expected.
Now I want to bring one additional option in the context menu of the target tree node that is ,when i right click on any of the target tree node in addition to the default menu options like "Collapse","Expand" i want to add one more option .For this i added "contextMenu" facet after the "nodeStamp" facet inside the tree.
*<f:facet name="contextMenu">*
*<af:popup id="p1">*
*<af:menu text="Delete" id="m1">*
*<af:commandMenuItem text="Delete" id="cmi1"*
*action="#{myWorkflow.deleteWorkflowNode}"/>*
*</af:menu>*
*</af:popup>*
*</f:facet*>
Now the problem is : before using drag and drop the context menu workes without any problem .But after using drag and drop the context menu is not popped up.
can anybody help me to resolve this?
Thanks,
Priya.

Hi Frank,
1. I am using JDeveloper 11.1.1.3 version
2. Drop target tree is having the context menu.
3. Yes . In Drop event am calling a backing bean method with return type DnDAction and i return the value as DnDAction.MOVE to reflect the changes in the database table to the target tree.

Hi,
Do you have a solution for this? Looking for exactly the same.
As far as I have it at the moment I have the backing object added to the attributes of the node:
<a4j:support event="oncontextmenu"
                                     oncomplete="#{rich:component('foldersContextMenu')}.doShow(event, {})"
                                     actionListener="#{customerBean.buildContextMenu}" reRender="foldersContextMenu, selectedNode">
                            <f:setPropertyActionListener value="#{item}" target="#{customerBean.nodeTitle}"/>
                            <f:attribute name="node" value="#{item}"/>
                        </a4j:support>This allows me to get the object in the backing bean:
public void buildContextMenu(ActionEvent event) {
        UIComponent component = event.getComponent();
        log.info("component: " + component.getId());
        Category node = (Category) component.getAttributes().get("node");
        log.debug("node : " + node);But how I translate that to setting this as the current node is causing me problems.
Thanks

Problems with right click in hierarchical tree

Hi,
I create a popup menu in a hierarchical tree and want to call this referencing to a node in the tree.
I can get the node in GET_TREE_NODE_SELECTION but the node need to be selected for this...
How can I select a node with a right click?? and then call the popup menu??
Am I clear??
Why the trigger MOUSE_CLICK doesn't works for right clicks??? I know about the SYSTEM.MOUSE_BUTTON_PRESSED but to use this I need a RIGHT_CLICK_TRIGGER... that I don't know how to call...
thanks!

Hi,
This is a bug(96289), the same as the Base bug 1477977 which has NOT been fixed in Release 9.0.2 (as Oracle anounced) or in any earlier releases.
Bug 1477977 was currently scheduled for the 1st patchset of Forms 9.0.4
I don't know if it was fixed. Contact Oracle about that.
Right now, to achive what you want you must left click to select a node. This means that the use must do a left click and a right click to have an item selected.

Right click tree node

Hello all,
I need to process right click on the tree node. I can get the node and process the action well. But the problem is that the selected node doesn't have a gray box (selection indicator) like when I left click it.
Please help me with this,
Thanks,
Fantabk

Dear Siva,
You can follow the following steps:-
- Create local class (eg:- lcl_screen_handler) as handler class.
- Define and implement methods handle_node_context_menu_req and handle_node_context_menu_sel for handling right click.
- In Method handle_node_context_menu_req use CALL METHOD menu->add_function for adding entries to context menu.
- In Method handle_node_context_menu_sel based on node_key and fcode handle logic for right click.
- Define event handler (eg:- grc_event_handler     TYPE REF TO lcl_screen_handler) to handle events for right click on tree.
- After creating Tree, specify events that are to be handled and assign them to tree instance
eg:- lwa_event-eventid = cl_simple_tree_model=>eventid_node_double_click.
      lwa_event-appl_event = ' '.   "system event, does not trigger PAI
      APPEND lwa_event TO lit_event. (where, lit_event TYPE cntl_simple_events)
- Also, register PAI for context menu as follows:-
Process PAI if context menu select event occurs
CALL METHOD grc_tree->set_ctx_menu_select_event_appl (where grc_tree is Tree instance)
    EXPORTING
      appl_event = 'X'.
- Register Tree events as follows:-
CALL METHOD grc_tree->set_registered_events
    EXPORTING
      events                    = lit_event ....
- Create event handler instance for tree
CREATE OBJECT grc_event_handler. (where, grc_event_handler is already declared on top)
- Set event handler method to handle various events on tree node
eg:- SET HANDLER grc_event_handler->handle_node_double_click FOR grc_tree.
        SET HANDLER grc_event_handler->handle_node_context_menu_req FOR grc_tree.
        SET HANDLER grc_event_handler->handle_node_context_menu_sel FOR grc_tree.
The events should be handled now. I have followed this approach and it worked for me.

Ashish

Right-clicking on sub-vi crashes LabView 7.0

When I right-click on a sub-vi on the block diagram, LabView crashes completely without any error messages.
I have uninstalled LabView and re-installed it and the device drivers, but it still happens. It doesn't matter which vi is open and which sub-vi is right-clicked on.
It only started doing this last week.

Back arrow will not drop down the recent history of pages visited on a right-click.

I use IE 11. Older versions of IE allowed you to back up to any previous page visited during the current session by right-clicking the back button. The right-click would drop down a list of pages visited, and you could choose any one of them, regardless
of their order. With IE 11, the right-click has no effect. I must left-click the back button and go through each page previously visited serially before reaching the desired one. Have I inadvertently changed a setting or something?

Hi,
Right-click on the back/forward button works from my side(IE 11 on Windows 8.1 and IE 11 on Windows 7 Ulimate SP1). Not sure what is your situation.
And there seems to be a bug related with IE 11 back button, see here:
IE 11 back button does not work
If you do not sure which settings have been modified, then we may consider to reset IE 11, and please take a note:
Resetting Internet Explorer isn't reversible, and all previous settings are lost after reset.
Here is a reference:
Change or reset Internet Explorer settings
Hope this may help

Labview edit time menu and right click popup menus

How can i add a menu item to the labview edit time menus and to the right click popup menu of any selected object in a block diagram?
I would like to integrate commonly used tools by me out of the springboard scripting tool into actual labview.
Solved!
Go to Solution.

It sounds to me like you are looking for something like the Right-Click Framework. Some people really like it, I have not used it extensively myself. I've had a request to convert a quick drop shortcut into a RCF plug-in, I'll see how it goes. I have also longed for a good way to hook into the LV IDE to add my own tools, what I find are useful, but not fully satisfactory solutions.
1) Right-Click Framework: Some initial startup costs in terms of downloading and installing. Start up is a bit slow (on my machine), and the workflow is a bit different than what I am used to: Select an object, press the hotkey, right-click. You can get used to it, but it is not as responsive as a built-in right-click since you can't right-click in one action. It seems to be easily extensible, I'll know more in a day or two.
2) Quick Drop: Built into LV. Slow startup like RCF. Fairly easily extensible. Not context aware (unless you build it in to your plug-in), so you have to choose your letters wisely. After the initial pain, the response time is not shabby, does require the extra Ctrl-Space action.
3) Tools Menu: I drop a few things in here, like my custom connector pane editor. Not bad, but there are no keyboard shortcuts (what a pain), so it is good for actions that you might call once or twice on a given VI.
In short, all of these methods require extra clicks or keypresses and are a bit sluggish. If something like copy and paste behaved this way we would never use LV again, but if your tool truly saves you a bunch of steps it is well worth it. I have almost run out of letters to use for my QD shortcuts.
Addedendum: Personally I am not quite ready to start talking to my computer, but LVSpeak seems pretty cool, Smashy Smashy.

Downloaded brushes not showing on right click drop-down list

I have recently reinstalled Photoshop cs5.1 and ran into a problem. My installed brushes are not showing up on my right click drop-down list. I took the old brushes and copied the folder to the new location. When I go to use these brushes there used to be a big drop down list when I right click anywhere on the canvas. It now only shows the basic brushes, but here is the thing though I can load and see them through the preset manager but they are not on my drop-down list like they were before I reinstalled.
I have noticed something odd as well this may help in the solution I have noticed that some files from Photoshop are saved on to my second hard drive, but I do not know if this is the cause.
The reason I reinstalled is my GPU acceleration wasn't working and had to reinstall to fix this. If any other information is needed I would be glad to share. This is just cutting into my workflow time since I have to load every single brush singlely and if I load them all I have to search through every single brush to find what I need.
Thank you!

I found a solution to my problem it may help others! I run Windows 7 64-bit this has two seperate folders for applications when installed. I did a windows search for one of the names of the available brushes on my right click list. The search showed me where the brushes were at. (Example: I searched in windows: DP Brushes) Aparently photoshop normally installs as a "32-bit" program in this location, C:\Program Files\Adobe\Adobe PhotoShop CS5.1\Adobe Photoshop CS5.1 (64 Bit)\Presets\Brushes it is here that I copied my new brushes to and it showed up again. Hope this helps anyone who was in my situation!

Firefox 6. When right clicking a tab no drop-down menu appears. Why do I not have the option to pin, unpin, etc.

I'm using Firefox 6 with all current updates. This is on a desktop pc running Windows XP (Service Pack 3).
At some previous time I was able to pin tabs - I pinned three. Lately I do not have a drop-down menu when right clicking on a pinned or unpinned tab. The feature is just not there.

Try the Firefox SafeMode. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
# You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
# Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />

How to display a seperate right click menu for each item of a tree control?

Hi I want to display a specific right click menu when a particular tree item is selected. I know how to create a menu and how to display it. I am using the function GetLabelFromIndex() to get the active tree item and then compare the label and based on the result display a manu for that item. Now my problem is that when I use the above function in the EVENT_RIGHT_CLICK it gives me the error "the Index passed is out of range" while using the same function with the same arguments in EVENT_SELECTION_CHANGE it gives no error...below is the part of my code
case EVENT_RIGHT_CLICK:
GetLabelFromIndex(panelHandle, PANEL_TREE, eventData2, label1);
//The function gives the stated error here
if(eventData1)//after it I compare the result and display the menu
case EVENT_SELECTION_CHANGE:
GetLabelFromIndex (panelHandle, PANEL_TREE, eventData2, label1);
//The function works fine here
if (eventData1)
If any one have any idea whats going on or alternate way of doing this Please share knowledge...Thanks
If you are young work to Learn, not to earn.

Hi,
one possible approach of solving this problem is looking closer at the error message: The error "the Index passed is out of range" tells you that something is wrong with the index, either it is too small or too large So why don't you set a breakpoint and check the index value, it might be useful information...
The other hint is to check the meaning of eventdata2 (using the help): It is different for different events! For the event_right_click it gives the horizontal mouse position, not the index as event_selection_change does...
