winIDEA Help

Version: 9.21.137


The Editor Window shows the content of the selected file in the project workspace. This usually starts with the display of the source code that contains the main() function being displayed in the Editor window. The Editor window also offers the options to set, clear and disable breakpoints and use Run/stop functions.



Elements of the Editor Window




Glyph margin

It shows where breakpoints can be/are set. In this region also line numbers can be displayed.






Lines, where breakpoints can be set.


Enabled breakpoints.


Disabled breakpoints.



Be careful with code that has been built with code optimization switched on!  Some code lines will not necessarily have a position where a breakpoint can be set although there is source code displayed at that line.  



Editor pane

Displays the source code or the content of any selected file or document.

Functionalites in Editor window for easier navigation:



Editor bar

List drop down of documents - If there is not enough space to show all document a drop down button EditorListButton  appears and it lists hidden documents.

  • Highlighted document - current top document.
  • Pinned documents.
  • Greyed out documents - pinned out documents.


Pinning/unpinning documents - Pin a document to stay in reach.

Context menus - Right-clicking on a document tab/empty space opens context menu with various close actions, open containing folder and copy name/path of the document.







Toggle Breakpoint

Set a breakpoint or clear an existing breakpoint:

1. Click Toggle Breakpoint button in the toolbar.

2. Press F9 key.

Context menu enables as well to Set Breakpoint/Disable/Clear Breakpoint.



Open dialog Execution Breakpoints.


Toggle Hardware Breakpoints

Set a hardware breakpoint or disable an existing hardware breakpoint.



Disabling and clearing/deleting breakpoints

winIDEA differentiate between disabled or cleared/deleted breakpoint:


Clear breakpoints

Disable breakpoints


Still visible, but do not execute

Have to be set again

Can be enabled again

Can not be found again

Can be used as a bookmark



Disabling breakpoints leaves a visible mark in the glyph margin making it easy to re-enable the breakpoint again if required.




winIDEA allows you to step through code in four different ways. Stepping can be also peformed at disassembly level.






Step into the next statement/function - Shortcut F11.

Step feature enables line-by-line code execution whilst examining variables and register content changes.


Step Over

Step over the next statement/function - Shortcut F10.

Enables the option to execute a entire function call and stop again when the starting point of the next line of code is reached.

Tip: Avoid Step over feature with software delay options because every instruction of binary code is executed individually.


Run Until

Run program until the current/specified position - Shortcut CTRL + F10 (or right-clicking Run until in the context menu).

Run Until function enables you quickly execute a portion of code without needing to set a breakpoint. It navigates you to either the next breakpoint or to the position where you clicked in the code depending on which one is next in program execution flow.  


Run Until Return

Run until current function exists - Shortcut SHIFT + F11.

Tip: Useful when examining the execution of the first few lines of a function using Step and then wanting to quickly execute the remainder of the function.



If unexpected behavior (jumping backwards or skipping lines of code, should occur, might be a result of the use of code optimization during compilation.



Context menu

Right-clicking within Editor pane opens context menu.





Toggle/Next/Previous Bookmark - Mark part, line of code/move to next or previous bookmark.


  • Tabify/Untabify Selection
  • Toggle line column - Insert/Remove line comment. (Shotrcut '/' )
  • Toggle block comment - Insert/Remove block comment. (Shortcut '*' )


Properties - See below.

Options - Open dialog Options to set fonts, colors , Whitespace, Auto-completion.

Open - Open C Header file.

Compile - Compile source file.

Next Error - Move to the next error in the code generated by the build manager.

Set Breakpoint, Run Until, Goto, Show Execution Point - Operate with Breakpoints.

Show Disassembly - Open Disassembly Window (if is not already open) and show disassembly from relevant line.

Auto Show Disassembly - Open Disassembly Window (if is not already open) and show disassembly when moving through the code.

Add File to Templates - Add file/document to templates to use it next time.

Highlight 'selected text' - If selected highlight selected text with 12 predefined colors






File Name - Displays the location of the file on disk. The user can select and copy the text.

Language - Select the appropriate programming language of the document. Upon first opening the file, the language is auto-detected from the file name extension, however, this detection may be incorrect if the file is not named according to commonly used conventions.

The Language selection affects syntax coloring, code folding and auto-completion, where available. If a language is not supported, the Text option should be selected. In such case, code folding and syntax coloring are not supported.

Encoding - The default encoding is set to the default setting in the user's installation of Windows. If characters are not displayed correctly, the correct encoding should be set. This setting is set for each file individually and does not affect the encoding settings globally. The UTF-8 encoding gives the best support for international documents and non-western characters.



Word highlighting

Command will highlight text in 12 predefined colors.



1. Select text or set a cursor/caret, double click and right-click to open the Context menu.

2. Select Highlight 'selected text'. This will mark all occurrences of this word in the document with an unique color.


Remove the highlight

Right-click inside the Editor window and in context menu select Remove all Highlights or Remove Highlight 'selected text'.
