When on a C++ line of code like the following
aType.aMethod(
std::make_shared< T_1>();
^^^^^-- Press tab here
)
Clion tries to move to the next parameter(i guess), but being the only parameter it goes nowhere. I want to have the tab to just insert characters(tab or space that is) and not to try to cycle the cursor among the method parameter. Is there a way to stop this alternative functionality?
I searched to no avail in
Settings|Editor|CodeStyle|C/C++
Thank you
"Try changing the "Next parameter" and "Previous parameter" keybindings to something else than Tab."

In addition to the accepted answer, i found that tab was assigned to Next Live Template Parameter Under : Main Menu | Navigate | Navigate in File (This is in the keymap section in settings, not the actual main menu). So when i generated definitions for the methods in my class and it jumped into the cpp if there were any auto generated functions with return initializer; as the method body it would jump to these instead of letting me indent code so i turned that off too and now i can happily implement the methods in order and fix those up when i get to them. Alternatively if you like that setting and want to keep it turned on, Hopefully knowing that you have to tidy up all instances of return initializer; before the tab key will indent code again is useful to you, i found it very confusing.
EDIT: i realise this wasn't part of the original question, but this is where googles top result brought me, so i hope you don't mind me adding this info here as its still related to the tab key doing weird things in CLion.

This has been really bugging me ever since I switched from VS 2015 to VS 2017.
Here's what's happening:
When I type this
for(int i = 0; i<v.size()
then add a semicolon, VS autocompletes the line to this:
for(int i = 0; i<v.size());
This is clearly not what I want, since I still need to type the increment portion of the for loop.
How do I prevent autocomplete for this specifically?
It is strange that you are typing this manually. Have you tried using stock code snippets? Type for and you should get a popup with for snippet selected -> press Tab to insert body and autoselect index variable type -> type new type -> press Tab to select index variable name and so on; finally press Enter to jump into loop body.
It's a bug that was introduced in VS2017. Make sure to bump the thread dedicated to this issue, and hopefully this will encourage the VS team to prioritize fixing this bug in a future release.
I've got a pretty old MFC application that's been touched by many people over the years (most of them probably not even CS guys) and it follows, what I like to call the "anarchy design pattern."
Anyway, one of the dialogs has a series of 56 vertical sliders and check boxes. However, there are additional sliders and checkboxes on the dialog as shown below.
Now, the problem is that the additional sliders and checkboxes take on IDs that are in sequence with the slider/checkbox series of the dialog. My task is to add more sliders and checkboxes to the series (in the blank space in the Slider Control group box) Unfortunately, since IDC_SLIDER57 through IDC_SLIDER61 are already in the dialog (same goes for the checkboxes), existing code, such as the snippet below will break:
pVSlider = (CSliderCtrl *)GetDlgItem(IDC_SLIDER1+i);
Is there a better way to modify the resource file without doing it manually? I've seen a third party tool called ResOrg that looks like it'll help do what I want, but the software is a bit pricey, especially since I'll only use it once. I guess I can give the demo a try, but the limitations might restrict me.
FYI, I'm using Visual C++ 6.0 (yes...I know, don't laugh, it's being forced upon me).
Instead of writing:
pVSlider = (CSliderCtrl *)GetDlgItem(IDC_SLIDER1+i);
you could write:
pVSlider = (CSliderCtrl *)GetDlgItem(GetSliderID(i));
where GetSlider is a function that returns the id of slider number i.
GetSlider function
int GetSliderID(int nslider)
{
static int sliderids[] = {IDC_SLIDER1, IDC_SLIDER2, IDC_SLIDER3, .... IDC_SLIDERn};
ASSERT(nslider < _countof(sliderids));
return sliderids[nslider];
}
With this method the IDC_SLIDERn symbols dont need to have sequential values.
I recently switched to QTCreator for C++ from Eclipse background.
I am looking for these two features in QtCreator...
(1) I want to open the file a class is written in by typing that class's name. For example Ctrl+Shft+T in Eclipse.
(2) I want to move back to where my cursor were before the current operation.
Any shortcuts for above two features?
To open the file of a class:
If you are in a file that is making use of the class, you can place the cursor on the class then press F2. By default, F2 is bound to the Follow Symbol Under Cursor action.
If you want to get to the class without to find an instance of it, you can use the Locator . By default Press:
ctrl + k to access the locator
Type c then space to locate classes
Now type the name of your class. Once you've selected the class, hit enter
To navigate back to where you were, you can use GoBack and GoForward, as mentioned by Roman Zaytsev. These default to alt + left and alt + right. It has been many years since I have used eclipse, but I thought it also used alt + left and right as I was pleased to find QtCreator used it as well.
(2) I want to move back to where my cursor were before the current operation.
Go to Tools > Options > Environment > Keyboard. There assign shortcuts for "GoBack" and "GoForward" in "QtCreator" section.
I'm new with Qt and I'm making a little application. I've do it with QWizard and QWizardPages.
I Have added 2 CustomButtons to the wizard so it has 5 buttons down: ButA, ButB, Back, Next/Finish, and Cancel.
ButA and ButB don't have to appear in all WizardPages. Eg:
WP0: just ButB
WP1: ButA and ButB
To do that, I have:
void WP0::initializePage()
{
wizard()->button(QWizard::CustomButton1)->setVisible(false);
}
With that when the app starts, you can't see butA. BUT if you go to the next page (where you see ButA and ButB) and then you click on BackButton, then you see ButA in WP0.
I supose that then you click on BackButton there is no call to WP0::initializePage() so my question is: how or where should I call that wizard()->button(QWizard::CustomButton1)->setVisible(false);
to never see ButA on WP0 ? Or what should I do?
I don't know if I understand your question completely. your description is kind of complicated. I think you should try button's events. It means you should call this function in press event or something like that and it's better that you define a boolean variable for true or false and call it by reference. I think this should solve your problem.
I am trying to add a Ctrl+F accelerator to my gtkmm textview program. I already implemented the search function into an gtk Entry field, so the only thing I need is to get focus the find entry when Ctrl+F is pressed.
I googled and checked tutorials/reference of gtkmm (2.4, I'm working with that) but the only things I found were accelerators in context with menus and toolbars using UIManager, which I don't have in that .cc file I use (and I can't add them, cause its an existing program).
I tried to add an action with an AccelKey on a button or tried the function add_accelerator() but I wasn't able to use them properly (I am pretty new to gtkmm and there aren't enough samples - at least none I understand). Here some examples I tried:
_gtkActionGroup->add(
Gtk::Action::create("find", "Find", "search in file"),
Gtk::AccelKey("<control>F"),
sigc::mem_fun(this, &SrcFilesView::onGtkTxtFindAccKeyPressed));
I didn't know how to add this action to the button (in the toolbar) I created...
_gtkAccelGroup(Gtk::AccelGroup::create()) //initialized in the constructor of the class
...
_gtkBtnFind.add_accelerator("find", _gtkAccelGroup, GDK_Find,
Gdk::ModifierType::CONTROL_MASK, Gtk::ACCEL_VISIBLE);
I tried here something, but I didn't really understand neither the parameters I needed to enter here nor how this method works - ofc it didn't work...
I'd be really happy if anyone can explain me how this things work properly and sorry for my bad english. If there are any things you need just tell me please. Thanks in advance
Greetings
edit: I looked up in the gtk sources and tried to understand the parameters of add_accelerator. Now I tried this but still doesn't work...:
_gtkBtnFind.add_accelerator("clicked", _gtkAccelGroup, GDK_KEY_F /* or better GDK_KEY_f ?*/,
Gdk::ModifierType(GDK_CONTROL_MASK), Gtk::AccelFlags(GTK_ACCEL_VISIBLE));
_gtkBtnFind.signal_clicked().connect(
sigc::mem_fun(this, &SrcFilesView::onGtkTxtFindAccKeyPressed));
UPDATE:
Okay I have understood most I think now, and I know why it doesn't work. The problem is that I have to add the accel_group to the window widget, but I got only a scrolled window and boxes in my program....and now I have no clue how to continue... :)
UPDATE2:
Alright I managed to do it without accelerators by using the "on_key_press_event" handler by checking the state and keyval parameter. Hope this helps some ppl at least ^^.
bool on_key_press_event(GdkEventKey* event) { /* declaration in my constructor removed */
if(event->state == GDK_CONTROL_MASK && event->keyval == GDK_KEY_f
|| event->state == (GDK_CONTROL_MASK | GDK_LOCK_MASK)
&& event->keyval == GDK_KEY_F) {
_gtkEntFind.grab_focus();
}
return false;
}
I would be still interested in a solution with the accelerators if there is any ! Greetings
