Merge bitcoin-core/gui#139: doc: Improve gui/src/qt README.md
5d1f260 Improve gui/src/qt README.md (Jarol Rodriguez) Pull request description: **Master/Before:** [Render of Master](https://github.com/bitcoin-core/gui/blob/master/src/qt/README.md) **PR/After:** [Render of PR](https://github.com/bitcoin-core/gui/blob/5d1f260713f9f1d29c0db68f2917dfe7368d4ba0/src/qt/README.md) **Changes:** The README.md found in `gui/src/qt` seems to not have gotten any love in a while. This PR fixes some grammatical errors, makes it easier to follow, and modernizes the logic of using Qt Creator. 1. Makes several sections more informative 2. Directories under `Files and Directories` now end with a forward slash denoting that they are a directory 3. Modernize the Qt Creator Logic for the current setup flow 4. Add UNIX Qt Creator Setup Instructions (Ubuntu & Debian) ACKs for top commit: RandyMcMillan: ACK 5d1f260 👍🏼 jonatack: ACK 5d1f260 Tree-SHA512: bd5cc24b95460f34a1efa489a6acc10d7632c84eabdcdc5729ef077d8303cf037ed664aae033af8883252433ea0999d8ec7d92e8b03d03a873d32b041a94f813

| See [CONTRIBUTING.md](/CONTRIBUTING.md) for general guidelines. | ||

|
||
| **Note:** Do not change `local/dash_en.ts`. It is updated [automatically](/doc/translation_process.md#writing-code-with-translations). | ||
|
|
||
| ## Using Qt Creator as an IDE | ||
|
|
||
| [Qt Creator](https://www.qt.io/product/development-tools) is a powerful tool which packages a UI designer tool (Qt Designer) and a C++ IDE into one application. This is especially useful if you want to change the UI layout. | ||
|
|
||
| #### Download Qt Creator | ||
|
|
||
| On Unix and macOS, Qt Creator can be installed through your package manager. Alternatively, you can download a binary from the [Qt Website](https://www.qt.io/download/). | ||
|
|
||
| **Note:** If installing from a binary grabbed from the Qt Website: During the installation process, uncheck everything except for `Qt Creator`. | ||
|
|
||
| ##### macOS | ||
|
|
||
| ```sh | ||
| brew install qt-creator | ||
| ``` | ||
|
|
||
| ##### Ubuntu & Debian | ||
|
|
||
| ```sh | ||
| sudo apt-get install qtcreator | ||
| ``` | ||
|
|
||
| #### Setup Qt Creator | ||
|
|
||
| * don't change `local/dash_en.ts`; this happens [automatically](/doc/translation_process.md#writing-code-with-translations) | ||
| 1. Make sure you've installed all dependencies specified in your systems build instructions | ||
| 2. Follow the compile instructions for your system, run `./configure` with the `--enable-debug` flag | ||
| 3. Start Qt Creator. At the start page, do: `New` -> `Import Project` -> `Import Existing Project` | ||
| 4. Enter `dash-qt` as the Project Name and enter the absolute path to `src/qt` as Location | ||
| 5. Check over the file selection, you may need to select the `forms` directory (necessary if you intend to edit *.ui files) | ||
| 6. Confirm the `Summary` page | ||
| 7. In the `Projects` tab, select `Manage Kits...` | ||
|
|
||
| ## Using Qt Creator as IDE | ||
| **macOS** | ||
| - Under `Kits`: select the default "Desktop" kit | ||
| - Under `Compilers`: select `"Clang (x86 64bit in /usr/bin)"` | ||
| - Under `Debuggers`: select `"LLDB"` as debugger (you might need to set the path to your LLDB installation) | ||
|
|
||
| You can use Qt Creator as an IDE. This is especially useful if you want to change | ||
| the UI layout. | ||
| **Ubuntu & Debian** | ||
|
|
||
| Download and install the community edition of [Qt Creator](https://www.qt.io/download/). | ||
| Uncheck everything except Qt Creator during the installation process. | ||
| Note: Some of these options may already be set | ||
|
|
||
| Instructions for macOS: | ||
| - Under `Kits`: select the default "Desktop" kit | ||
| - Under `Compilers`: select `"GCC (x86 64bit in /usr/bin)"` | ||
| - Under `Debuggers`: select `"GDB"` as debugger | ||
|
|
||
| 1. Make sure you installed everything through Homebrew mentioned in the [macOS build instructions](/doc/build-osx.md) | ||
| 2. Use `./configure` with the `--enable-debug` flag | ||
| 3. In Qt Creator do "New Project" -> Import Project -> Import Existing Project | ||
| 4. Enter "dash-qt" as project name, enter src/qt as location | ||
| 5. Leave the file selection as it is | ||
| 6. Confirm the "summary page" | ||
| 7. In the "Projects" tab select "Manage Kits..." | ||
| 8. Select the default "Desktop" kit and select "Clang (x86 64bit in /usr/bin)" as compiler | ||
| 9. Select LLDB as debugger (you might need to set the path to your installation) | ||
| 10. Start debugging with Qt Creator (you might need to the executable to "dash-qt" under "Run", which is where you can also add command line arguments) | ||
| 8. While in the `Projects` tab, ensure that you have the `dash-qt` executable specified under `Run` | ||
| - If the executable is not specified: click `"Choose..."`, navigate to `src/qt`, and select `dash-qt` | ||
| 9. You're all set! Start developing, building, and debugging the Dash Core GUI |
