function(

text : string,
|
|
[percentage : boolean],

[cancel_callback : function]

Create a new progress_bar displayed in [darktable.gui.libs.backgroundjobs](../libs/backgroundjobs.md)
|
|
|
|
* **text** - _string_ - The text to display in the job entry
|
|
* **\[percentage\]** - _boolean_ - Should a progress bar be displayed
|
|
* **\[cancel_callback\]** - _[function](#cancel_callback)_ - A function called when the cancel button for that job is pressed. Note: the job won't be destroyed automatically. You need to set [types.dt_lua_backgroundjob_t.valid](../../types/dt_lua_backgroundjob_t#valid) to false for that.
|
|
|
|
* **return** - _[types.dt_lua_backgroundjob_t](../../types/dt_lua_backgroundjob_t)_ - The newly created job object
|
|
|
|
## cancel_callback
|
|
```
|
|
function(
|
|
job : types.dt_lua_backgroundjob_t
|
|
)
|
|
```
|
|
|
|
* **job** - _[types.dt_lua_backgroundjob_t](../../types/dt_lua_backgroundjob_t)_ - The job that is being cancelled
