Member Typedef Documentation

base

using xtd::forms::control::control_collection::base

Represents the base type of the collection.

Constructor & Destructor Documentation

control_collection() [1/2]

xtd::forms::control::control_collection::control_collection ( )

explicitdefault

Creates a new object xtd::forms::control::control_collection with specified allocator (optional).

Remarks

If allocator not specified, the std::allocator<value_type> is used.

control_collection() [2/2]

xtd::forms::control::control_collection::control_collection ( bool keep_cloned_controls )

explicit

Creates a new object xtd::forms::control::control_collection with specified keep_cloned_controls, and allocator (optional).

Parameters

keep_cloned_controls

If true the collection clone and keep controls; otherwise none.

Remarks

If allocator not specified, the std::allocator<value_type> is used.

Warning

Internal use only

Member Function Documentation

operator[]() [1/2]

std::optional< value_type > xtd::forms::control::control_collection::operator[]

(

const xtd::string &

name

)

const

Gets the first xtd::forms::control::control_collection in the list with the specified name.

Parameters

name	The name of the xtd::forms::control to get from the list.

Returns

The first xtd::forms::control in the list with the given Name. This item returns optional with no value if no xtd::forms::control with the given name can be found.

Remarks

The operator [] property is case-sensitive when searching for names. That is, if two controls exist with the names "Lname" and "lname", operator [] property will find only the xtd::forms::control with the xtd::forms::control::name() that you specify, not both.

operator[]() [2/2]

std::optional< value_type > xtd::forms::control::control_collection::operator[]

(

const xtd::string &

name

)

Gets the first xtd::forms::control::control_collection in the list with the specified name.

Parameters

name	The name of the xtd::forms::control to get from the list.

Returns

The first xtd::forms::control in the list with the given Name. This item returns optional with no value if no xtd::forms::control with the given name can be found.

Remarks

The operator [] property is case-sensitive when searching for names. That is, if two controls exist with the names "Lname" and "lname", operator [] property will find only the xtd::forms::control with the xtd::forms::control::name() that you specify, not both.

emplace_front()

template<class control_t, class ... args_t>

control_t & xtd::forms::control::control_collection::emplace_front ( args_t &&... args )

inline

Creates and inserts specified control at specified position.

Parameters

pos	The iterator before which the content will be inserted. pos may be the xtd::forms::control::control_collection::end iterator.
args	The arguments to forward to the create method of the control

Returns

A reference to the created control.

Remarks

The control will be destroyed automatically when the control no longer has a parent.

For creation and insertion, this method uses the xtd::forms::control::create methods of the various controls.

Examples

The folowing example demonstartes the use of xtd::forms::control::control_collection::emplace, xtd::forms::control::control_collection::emplace_at and xtd::forms::control::control_collection::emplace_back methods.

#include <xtd/xtd>
 
auto main() -> int {
  auto button1_clicked = 0, button2_clicked = 0;
  auto form1 = form::create("Emplace example");
  form1.controls().emplace_front<button>("Button 1", point{50, 50}).click += delegate_ {
    form1.controls()["label1"].value().get().text(string::format("Button 1 clicked {} times", ++button1_clicked));
  };
  form1.controls().emplace_at<button>(1, "Button 2", point {50, 100}, drawing::size {200, 75}).auto_repeat(true).click += delegate_ {
    form1.controls()["label2"].value().get().text(string::format("Button 2 clicked {} times", ++button2_clicked));
  };
  form1.controls().emplace_at<label>(2, "Button 1 clicked 0 times", point {50, 200}, drawing::size {200, 23}, "label1");
  form1.controls().emplace_back<label>("Button 2 clicked 0 times", point {50, 230}, drawing::size {200, 23}, "label2");
  application::run(form1);
}

emplace_at()

template<class control_t, class ... args_t>

control_t & xtd::forms::control::control_collection::emplace_at ( size_t index, args_t &&... args )

inline

Creates and inserts specified control at specified position.

Parameters

index	The index before which the content will be inserted.

emplace_back()

template<class control_t, class ... args_t>

control_t & xtd::forms::control::control_collection::emplace_back ( args_t &&... args )

inline

Creates and adds a control to the end.

Parameters

args	The arguments to forward to the create method of the control

Returns

A reference to the created control.

Remarks

The control will be destroyed automatically when the control no longer has a parent.

For creation and insertion, this method uses the xtd::forms::control::create methods of the various controls.

Examples

The folowing example demonstartes the use of xtd::forms::control::control_collection::emplace, xtd::forms::control::control_collection::emplace_at and xtd::forms::control::control_collection::emplace_back methods.

#include <xtd/xtd>
 
auto main() -> int {
  auto button1_clicked = 0, button2_clicked = 0;
  auto form1 = form::create("Emplace example");
  form1.controls().emplace_front<button>("Button 1", point{50, 50}).click += delegate_ {
    form1.controls()["label1"].value().get().text(string::format("Button 1 clicked {} times", ++button1_clicked));
  };
  form1.controls().emplace_at<button>(1, "Button 2", point {50, 100}, drawing::size {200, 75}).auto_repeat(true).click += delegate_ {
    form1.controls()["label2"].value().get().text(string::format("Button 2 clicked {} times", ++button2_clicked));
  };
  form1.controls().emplace_at<label>(2, "Button 1 clicked 0 times", point {50, 200}, drawing::size {200, 23}, "label1");
  form1.controls().emplace_back<label>("Button 2 clicked 0 times", point {50, 230}, drawing::size {200, 23}, "label2");
  application::run(form1);
}

insert()

void xtd::forms::control::control_collection::insert ( size_t index, const control_ref & value )

overridevirtual

Inserts specified element at specified index.

Parameters

index	The index before which the content will be inserted.
value	The element to insert.

Reimplemented from xtd::forms::layout::arranged_element_collection< control_ref >.

on_item_removed()

void xtd::forms::control::control_collection::on_item_removed ( size_t index, control_ref & item )

inlineoverrideprotectedvirtual

Raises the xtd::forms::layout::arranged_element_collection::item_removed event.

Parameters

index	The index of the item.
item	The item removed.

Reimplemented from xtd::forms::layout::arranged_element_collection< control_ref >.
