Constructor & Destructor Documentation

◆ progress_dialog()

xtd::forms::progress_dialog::progress_dialog ( )

Initializes a new instance of the progress_dialog class.

Member Function Documentation

◆ cancelled()

bool xtd::forms::progress_dialog::cancelled ( ) const

Gets whether user has clicked on cancel button.

Returns: true if user has clicked on cancel button; otherwise false.

◆ dialog_appearance() [1/2]

xtd::forms::dialog_appearance xtd::forms::progress_dialog::dialog_appearance ( ) const

noexcept

Gets the dialog appearance.

Returns: One of the xtd::forms::dialog_appearance values. The default value is xtd::forms::dialog_appearance::standard.

◆ dialog_appearance() [2/2]

progress_dialog& xtd::forms::progress_dialog::dialog_appearance ( xtd::forms::dialog_appearance dialog_appearance )

Sets the dialog appearance.

Parameters

dialog_appearance One of the xtd::forms::dialog_appearance values. The default value is xtd::forms::dialog_appearance::standard.

Returns: Current progress dialog.

◆ hide()

void xtd::forms::progress_dialog::hide ( )

Hides progress dialog box.

◆ increment()

void xtd::forms::progress_dialog::increment ( int32 increment )

Advances the current position of the progress bar by the specified amount.

Parameters

increment The amount by which to increment the progress bar's current position.

Remarks: The increment method enables you to increment the value of the progress bar by a specific amount. This method of incrementing the progress bar is similar to using the step property with the perform_step method. The value property specifies the current position of the progress_bar. If, after calling the increment method, the value property is greater than the value of the maximum property, the value property remains at the value of the maximum property. If, after calling the increment method with a negative value specified in the value parameter, the Value property is less than the value of the minimum property, the value property remains at the value of the minimum property.; Because a progress_bar object whose style is set to marquee displays a continuously scrolling bar instead of its value, calling increment is unnecessary and will do nothing.

◆ informations() [1/2]

const std::vector<xtd::ustring>& xtd::forms::progress_dialog::informations ( ) const

noexcept

Gets the information texts.

Returns: The information texts.

◆ informations() [2/2]

progress_dialog& xtd::forms::progress_dialog::informations ( const std::vector< xtd::ustring > & informations )

Sets the information texts.

Parameters

informations The information texts.

Returns: Current progress_dialog instance.

◆ marquee() [1/2]

bool xtd::forms::progress_dialog::marquee ( ) const

noexcept

Gets a value that Indicates progress by continuously scrolling a block across a progress_bar in a marquee fashion.

Returns: tree is marquee; otherwise false. The default is false.

◆ marquee() [2/2]

progress_dialog& xtd::forms::progress_dialog::marquee ( bool marquee )

Gets a value that Indicates progress by continuously scrolling a block across a progress_bar in a marquee fashion.

Parameters

marquee tree is marquee; otherwise false. The default is false.

Returns: Current progress_dialog instance.

◆ marquee_animation_speed() [1/2]

size_t xtd::forms::progress_dialog::marquee_animation_speed ( ) const

noexcept

Gets he time period, in milliseconds, that it takes the progress block to scroll across the progress bar.

Returns: The time period, in milliseconds, that it takes the progress block to scroll across the progress bar.

Remarks: A marquee-style progress indicator does not display progress; instead it indicates that an operation is occurring by moving the progress block across the progress bar.; Since the marquee animation speed is a time period, setting the value to a higher number results in a slower speed and a lower number results in a faster speed.

◆ marquee_animation_speed() [2/2]

progress_dialog& xtd::forms::progress_dialog::marquee_animation_speed ( size_t marquee_animation_speed )

Sets the time period, in milliseconds, that it takes the progress block to scroll across the progress bar.

Parameters

marquee_animation_speed The time period, in milliseconds, that it takes the progress block to scroll across the progress bar.

Remarks: A marquee-style progress indicator does not display progress; instead it indicates that an operation is occurring by moving the progress block across the progress bar.; Since the marquee animation speed is a time period, setting the value to a higher number results in a slower speed and a lower number results in a faster speed.

◆ maximum() [1/2]

int32 xtd::forms::progress_dialog::maximum ( ) const

noexcept

Gets the maximum value of the range of the control.

Returns: The maximum value of the range. The default is 100.

Remarks: This property specifies the upper limit of the value property. When the value of the maximum property is changed, the progress_bar control is redrawn to reflect the new range of the control. When the value of the value property is equal to the value of the maximum property, the progress bar is completely filled.; You can use this property to specify a value to which the value property must be set (by setting the value property or using the increment or perform_step methods) to indicate that an operation is complete. For example, you can set the value of the maximum property to the total number of files in a file copy operation. Each time a file is copied, the value property can be increased by 1 until the total number of files is copied. At that point, the progress bar would be completely filled.

◆ maximum() [2/2]

progress_dialog& xtd::forms::progress_dialog::maximum ( int32 maximum )

Sets the maximum value of the range of the control.

Parameters

maximum The maximum value of the range. The default is 100.

Remarks: This property specifies the upper limit of the value property. When the value of the maximum property is changed, the progress_bar control is redrawn to reflect the new range of the control. When the value of the value property is equal to the value of the maximum property, the progress bar is completely filled.; You can use this property to specify a value to which the value property must be set (by setting the value property or using the increment or perform_step methods) to indicate that an operation is complete. For example, you can set the value of the maximum property to the total number of files in a file copy operation. Each time a file is copied, the value property can be increased by 1 until the total number of files is copied. At that point, the progress bar would be completely filled.

◆ minimum() [1/2]

int32 xtd::forms::progress_dialog::minimum ( ) const

noexcept

Gets the minimum value of the range of the control.

Returns: The minimum value of the range. The default is 0.

Remarks: This property specifies the lower limit of the value property. When the value of the minimum property is changed, the progress_bar control is redrawn to reflect the new range of the control. When the value of the value property is equal to the value of the minimum property, the progress bar is empty. To change the value of the progress bar, use the step property with the perform_step method, use the increment method, or set the value of the value property directly.

◆ minimum() [2/2]

progress_dialog& xtd::forms::progress_dialog::minimum ( int32 minimum )

Sets the minimum value of the range of the control.

Parameters

minimum The minimum value of the range. The default is 0.

Returns: Current progress_dialog instance.

Remarks: This property specifies the lower limit of the value property. When the value of the minimum property is changed, the progress_bar control is redrawn to reflect the new range of the control. When the value of the value property is equal to the value of the minimum property, the progress bar is empty. To change the value of the progress bar, use the step property with the perform_step method, use the increment method, or set the value of the value property directly.

◆ perform_step()

void xtd::forms::progress_dialog::perform_step ( )

Advances the current position of the progress bar by the amount of the Step property.

Remarks: The perform_step method increments the value of the progress bar by the amount specified by the step property. You can use the Step property to specify the amount that each completed task in an operation changes the value of the progress bar. For example, if you are copying a group of files, you might want to set the value of the step property to 1 and the value of the maximum property to the total number of files to copy. When each file is copied, you can call the perform_step method to increment the progress bar by the value of the step property. If you want to have more flexible control of the value of the progress bar, you can use the increment method or set the value of the value property directly.
