The taskbar in Qt Design Studio can display following types of output:
- Search Results
- Application Output
- Compile Output
- QML Debugger Console
- General Messages
- Version Control
Output is available on the taskbar in all modes.
You can view output in the following ways:
- Select the output view on the taskbar.
- Select Alt (Cmd on macOS) and the number of the view on the taskbar.
- Select , and then select the view to open.
- Select View > Output. The menu items also display the keyboard shortcuts that you can use.
To maximize an open output view, select the (Maximize) button or press Alt+Shift+9.
To increase or decrease the output text size, select (Zoom In) or (Zoom Out), or press Ctrl++ or Ctrl+-. Zooming is not supported in all output views.
If the text in the output is not displayed correctly, Qt Design Studio might be using a different codec from the one used by the tools that generate the output. To specify the codec to use, select Edit > Preferences > Environment > Interface, and then select the codec in the Text codec for tools field.
To search from output, press Ctrl+F when the view is active. Enter search criteria in the Find field. For more information, see Finding and Replacing.
Besides searching from the output, you can enter a string in the Filter field to filter it. To specify filtering options, select the "Filtering options menu" button. You can filter output by using regular expressions or case-sensitivity. Select Show Non-matching Lines to hide the lines that match the filter.
Finding and filtering are not supported in all output views.
Issues lists the following types of issues:
- Asset Importer Error - Errors and warnings encountered while importing assets from a design tool.
- Build System - Errors and warnings encountered during a build.
- Compile - Selected output from the compiler. Open Compile Output for more detailed information.
- Debug Information - Lists debug information packages that might be missing.
- Debugger Runtime - Errors encountered when starting Qt Design Studio. For example, information about missing DLLs.
- Deployment - Errors encountered between building an application successfully and starting it on a device.
The view filters out irrelevant output from the build tools and presents the issues in an organized way. To further filter the output by type, select (Filter Tree) and then select a filter.
Select one or several lines to apply context-menu actions to their contents. You can remove the selected lines or copy their contents to the clipboard. For single lines, you can search the Internet for a solution using the contents of the line as search criteria or open a version control annotation view of the line that causes the error message.
To navigate to the corresponding source code, click an issue or select Show in Editor in the context menu. The entry must contain the name of the file where the issue was found.
To view more information about an issue in Compile Output, select Show Output in the context menu.
To jump from one issue to the next or previous one, press F6 and Shift+F6.
By default, a new build clears the Issues view. To keep the issues from the previous build rounds, deselect Edit > Preferences > Build & Run > General > Clear issues list on new build.
In Search Results, you can search through projects, files on a file system or the currently open files:
The search history (1) stores the search results. You can select earlier searches from the history.
The figure below shows an example search result for all occurrences of the search string in the specified directory.
For more information about the different search options, see Finding and Replacing.
Application Output displays the status of a program when you execute it, and the debug output.
Select toolbar buttons to run applications, to attach the debugger to the running application, and to stop running or debugging.
To specify settings for displaying application output, select Edit > Preferences > Build & Run > Application Output, or click the (Open Settings Page) button. You can select whether to open Application Output on output when running or debugging applications, to clear old output on a new run, to word-wrap output, and to limit output to the specified number of lines.
Compile Output shows all output from the compiler. The Compile Output is a more detailed version of information displayed in Issues.
Double-click on a file name in an error message to open the file in the code editor.
Select the Cancel Build button to cancel the build.
To specify whether to open the Compile Output view on output when building applications, select Edit > Preferences > Build & Run > Compile Output, and then select the Open Compile Output when building check box. In the Limit output to field, you can specify the maximum amount of build output lines to display.
You can also open the preferences page by clicking (Open Settings Page).
To copy the output to the clipboard, select Select All in the context menu, and then select Copy. Save the output as a file if you want to examine it later without having to build the project again. This is useful for large projects that take a long time to build.
You can use Qt Design Studio's output parsers to parse output from builds done outside of Qt Design Studio or stored from previous build runs. By default, the parsers from the kit selected for the active project are used, but you can select another kit.
To parse compile output:
- Select Tools > Parse Build Output.
- Paste the build output in the Build Output field, or select Load from File to load it from a file.
- Deselect the Output went to stderr check box if the parser expects issues on
- In the Use parsers from kit field, select the kit to use for parsing the output. Select Manage to view and modify kit settings.
- The parser displays the parsed output in Issues. By default, the view is cleared before adding the new output. Deselect the Clear existing tasks check box to append the new output to the old output.
- Select OK to start parsing.
