Put the X on the tab it goes with.

This X just closes out of the tab that is on top.

Pretty much every other program with tabs has the X on the tab you’re closing out of. The current placement makes me hesitate every time, because it feels like you’re X-ing out of the entire code-viewing pane, not just the single file you want to close.

It’s also not consistent with the rest of the environment.

For example, in the pane on the bottom in the screenshot above, “Threads” and “Wa tch” look like two tabs, but clicking the X in that pane causes the entire pane to disappear rather than just closing the tab that is on top.

Doing a CTRL+F and finding all instances of a word works, but is a lot of steps. I tend to use Notepad++ a lot for my IDE and it has this really handy feature. If you double-click a word, it will highlight that and all other instances of that word inside that one open file. This is like a "quick find" that saves a lot of time. See attached image to get the idea. The darkest highlight is the one instance that was double-clicked.

Fix the exit function

It has been suggested much earlier here, but obviously passed out of mind:

When using 'Go to Definition' (CTrl+I) while in release configuration, CVI tells that no source code information was found for the identifier '...', because 'Browse information is not available in the Release configuration'... (still true for CVI2010)

This can and should be improved!

And it might be a good opportunity to also add the reverse process, 'Goto Declaration', suggested here

Integrated mouse wheel support

Hello,

I am glad that the event EVENT_MOUSE_WHEEL_SCROLL was added some time earlier to CVI. In principle, now it is possible to operate numeric controls, ring controls, etc. not only via keyboard and mouse, but also via the mouse wheel. This allows very smooth operations, great!

However, the integration level is inconsistent: While pressing the ARROW_UP key on a selected control will increase the value displayed in the control automatically, i.e. without the need of the programmer to react to a specific event, achieving the same result with the mouse wheel requires adding code to each callback. This is possible, but inconvenient as it adds a lot of overhead.

Right now, in every callback of a numeric or ring control that shall support the mouse wheel I have the following lines:

    switch ( event )
    {
        case EVENT_MOUSE_WHEEL_SCROLL:
            if ( eventData1 == MOUSE_WHEEL_SCROLL_UP )
            {
                FakeKeystroke ( VAL_UP_ARROW_VKEY );
            }
            else if ( eventData1 == MOUSE_WHEEL_SCROLL_DOWN )
            {
                FakeKeystroke ( VAL_DOWN_ARROW_VKEY );
            }

            break;
        case EVENT_VAL_CHANGED:
    ...

Hence I suggest

either to treat a mouse wheel on a selected control like an ARROW_UP or ARROW_DOWN keypress (personally preferred)
or to add one more attribute allowing to treat a mouse wheel on a selected control like an ARROW_UP or ARROW_DOWN keypress. In the UI editor, then there should be a checkmark (allow mouse wheel support), similar to the check marks initially dimmed etc. This attribute could be useful if there are concerns of backward compatibility - may be some users don't want to support the mouse wheel...

Thanks!

Auto Indent Code

While developing code, having correct indentations is very helping in making sure you have all the right brackets and to see where your structures are nested easily. Sometimes, whether by copying and pasting or just rapidly getting out a section of code, a whole segment might have incorrect indentation, which is tedious to correct.

This is where an auto indent tool could be a big time saver. From somewhere like the Edit menu, where similar functionality is located in other development environments, you could select Format Selection to do a highlighted section or Format File to do the whole file. Then, CVI can format the tabs for you:

Although this is a simple example, auto indent becomes even more useful when you have multiple nested structures and decide, for instance, to add or remove another nested loop.

Hello,

imho the nice tool tips feature provided by the Programmer's Toolbox leads a miserable existence, because it is extra effort integrating it into a GUI.

I would love to see the tool tips integrated into the IDE, that is, when editing a control in the GUI editor, I would like to be able to also set the tool tips text and if it is initially enabled, just like it is possible to enter a control label text. This would include moving the tool tips from the Toolbox to the regular user interface library.

Many Thanks!

Improved variable view

Hello,

Lets' assume a small structure or small array that one would like to have a look at during debugging. Selecting 'View Variable Value' (or Shift+F7) in the IDE puts the cursor on the corresponding line in the variable editor. If there are several variables, the variable of interest typically is in the last line of the variable editor. Now if one is interested in any element of the structure, it is always necessary to scroll down, which is quite inconvenient.

Hence I suggest to place the selected variable at the top of the variable view, allowing to see its first elements without scrolling.

Thanks

Hello,

in the IDE of CVI it is possible to have both a toolbar and a status bar. Now if a file has been changed and could be saved, the disk icon is undimmed in both the status bar and the tool bar. For the tool bar, a single click is sufficient to save, while the status bar requires a double click.

While this double click behavior is true for all status bar actions (lock, unlock...), personally I would find it less irritating if the staus bar also would react on single clicks instead of double clicks.

Thanks for consideration,

Wolfgang

Hi all !

I have some idea , it's a small thing but it can really help ,

When working with multiple C / H files you can switch between the open files easily in the files bar above the code area.

But when I'm closing the CVI and re opening it the files position in the changes , if i not mistaken i think the it's re ordering it by the previous stack status.

It would be nice to have the option to set a file order that will remain even after shut down.

Thank you.

Graph improvements

Hello,

I have 2 suggestions for graph improvements.

1/ I suggested the first one a long time ago but it has never been implemeted so I try again trough this idea exchange board.

I would like to have the possibility to change the grid lines style to dash or dot. Today only solid is available.

I have written a routine to do it for printing graphs but as you can see it in the attachment it is not always working properly.

2/ It would be nice to have the possibility to set a percentage of transparency for the plots. In the example attached you can see if the green plot would have been behind the blue some parts would not have been visible. By setting the percentage of transparency of the blue one the green if behind the blue would become partly visible.

These 2 features are already available in the 3D graph so it would be nice to have them also on 2D plots.

Regards

Bertrand
